Divine Delta - AREA DVD (Germany)

"Well done, XTZ The Divine Delta is visually an impressive appearance, the beautiful optics combined with exemplary processing. If you then connect the large bookshelf speaker, you can immerse yourself deeply in any musical world, and no matter what kind of music it is. Either club music, classical music, jazz or pop, does not matter at all: The delta always plays sovereign, always cultivated, extremely pleasant, at the same time dynamic and with extreme SPL capabilities - for the money invested almost unrivaled at present."

Spirit SUB 12 - Hemmabio (Sweden)

August 03 - 2018

"A thoughtful product like this one is fun to review because I can give a wholehearted recommendation, but it's hard for me not to make a brainwashed impression when I'm not expressing any direct criticism. Personally, I like black or slightly snowy dark wood. But anyone who wants to use the subwofer in a home cinema will appreciate the matt black, while the matt white is more suitable for modern living spaces. RCA outputs are no important detail, but it is also missing if we are to dig into any shortcomings. In other words, this subwoofer is good, really really good."

EDGE A2-300 - Audiophile Magazine (Thailand)

July 23 - 2018

"A2-300 has passed my test of power and dynamic when I listen at high volume level with enormous bass music. I continue using high sound level but the chassis is only warm for my touch. This is normal to the ICEpower amp. I found that the frequency response is very stable and precise. It has good sound since the first minute after turn on, no need to wait for ten more minutes like other amps. The reserved power push music with like liked and musicality with truthful presentation. With various kinds of music, vocals, pops, any reordings, it generates sound with openness and no hiding..."This is the dream amplifier which is easy to use and you can live long with it. Anyone who is looking this style of amplifier, this is the golden opportunity for you."

June 18 - 2018

"Actually, I do not know any power amp - sorry for the somewhat flat-looking, but true statement - that delivers so much for so little money. It is not just the sheer sine wave power of the XTZ Edge A2-300, but the sound as well. On the plus side there is a strong, fast bass range, an astonishingly "analogous", almost tube-like fine midrange resolution, impressive coarse and fine dynamics as well as a stage construction, which is characterized by a clean, accurate presentation and a lively, non-dissecting sound. If you add price, workmanship and practicality (it's not a problem to put it in your laptop bag), you can only congratulate the manufacturer for the XTZ Edge A2-300. "

For us the XTZ Divine Delta is certainly the reference in this price range, this time we have found nothing to complain about and deserve her our highest award. "

"In our test cinema, the XTZ set was able to implement 100 percent of its laboratory-determined advantages and played at a particularly high level. The perfect tonality of the entire set and its balanced dispersion characteristics, which forms the basis for precise spatiality, really appealed to us. Even acoustically very complex scenes from films like "Lone Survivor" or "Edge of Tomorrow" were solved wonderfully by the Cinema-M8-Set and left dialogues crystal clear above everything else without dissecting the whole picture or even destroying it."

"When writing these lines in the conclusion, I notice that in the above description of sound I delivered the greatest compliment for the XTZ basically en passant: All speakers, which came to my mind as a benchmark, are, concerning the price level, at least one level above the Alpha. This clearly reveals the level at which the XTZ Divine Alpha plays: resolution / transparency, dynamics, airiness, long-term fitness and neutrality are on an absolute high-end level, also in the range far above 10.000€ there is not (much) more to get."

"It is difficult to find a subwoofer to fully fill a 200 sqft area with high dynamic low bass at the same price point of SUB 1×12. I am sure that higher price model would have at ease of fulfilling that, but that would be another story to tell. If you are in the market for a natural cinema sounding subwoofer, but also be able to tune for your personal taste/preference in bass, you should definitely give XTZ Cinema SUB 1×12 a try."

"99/100 Points" "Based on a well-tuned, deep and clearly structured bass, the sound of the 99.36 FLR is accentuated by a variety of timbres, a high degree of transparency and detail, as well as a concise and vivid representation of vocals. The testers especially liked the way the Fountek ribbon tweeter played, which doesn't contain any kind of tonal hardship or hissing." "With their sonic abilities, the XTZ 99.36 FLR catapults itself into the high-end league of passive speakers and is now the Technic3D reference in the price group around 1500€ / pair."

All these possibilities make the Tune 4 more than just a great speaker, whether in the sound itself, or in the quality of the cabinet and its overall features. The speaker provides an amazing dynamic range and amount of details, also the bass qualities are astonishing. If you need more, you can also easily connect a subwoofer to the subwoofer-output."

"There are not many options for really good sound on the desk. We have already tested the Quadral Rondo Active and they are certainly a good alternative but still I find that the Tune 4 gives a better insight into the music with more timbre and details in the sound. Furthermore the Dirac DSP gives you a unique opportunity to adjust the sound as you like. Whether you're working, surfing or just sitting in front of the screen, the Tune 4 always make an excellent impression. The Speakers can also be used to support the TV sound, for example, via the optical input and it definitely sounds better than any soundbar! "

Weaknesses are looked for in vain." "The competitors are also strong, but the XTZ impresses with its high acoustic harmony and the absolutely identical handling of music and movie source material. Very high SPL capabilities and an outstanding precision, even with parallel occuring bass effects, are part of the  impressive performance."

Produkt: EDGE A2-300
I am very pleased with the amp. i am able to squeeze my 2.1 budget system effortless (Marantz , Micca RB42 ). in the future i will buy another edge and use them both as mono block for an Ohms Walsh speaker set in my new home . they arrived perfectly to Calgary AB. Canada
Produkt: EDGE A2-300
Using the Edge A2-300 alongside several Emotiva PA-1 amps (now discontinued) which use the same ICEpower core. The sound is indistinguishable, which is to say of great clarity and detail. Shipping to the US took under a week, and the unit arrived well boxed.
Hi I have received my XTZ 10.17 Edge subwoofer today. Wow. Beautiful gloss black finish. Sound is awesome. I have heard many subwoofers including Rel and have owned a Bowers and Wilkins asw4000. This thing really is amazing for its size. Bass is super tight on par with the Bowers and Wilkins. Not as loud or quite as deep but it is less than a quarter of the size and looks so much nicer. I have been searching for a good subwoofer that is small enough to fit in my room but doesn't compromise on sound. I have found it. Truly surprised. It's magic. I was a bit worried if had made the right decision to buy something without hearing it for myself and was unsure of whether I should have gone for the 12.17 edge but I'm glad to say I think I'm made the right decision. Thanks
Produkt: EDGE A2-300
Just took delivery of this amp today and it’s hooked up to Dali Menuets on my desk fed by Tidal streaming through my ipad and Oppo HA2 on lineout. This is a fabulous set up and I’ve already had my first goosebump moment. I was a bit worried about it having too much power but the little attenuation knob on the rear has limited that risk nicely so no problems. I might struggle to get any work done now as everything sounds superb. Fits neatly on the desk and I think the form-factor is terrific. Great job XTZ!
Produkt: SUB 8.17
I’ve bought two 8.17 subwoofers mainly for stereo. They acompany my Kef LS50 W Active speakers. So now I have a complete active full range stereo setup. These little subwoofers are wonderfull.. they are powerfull and go as deep as 29 Hz in my 45 square meters room. I use Roon DSP for room correction (measured with REW) and add a housecurve with the KEF DSP. Crossovers are set internal in the Kef DSP, 80 hz for the Kef and 85 Hz for the 8.17 Now I have a powerfull clean and detailed bass and because the Kefs doesn’t have to play the deepest bass, they sound clean and fast in the midrange and highs. Thank you XTZ for these fantastic little subwoofers. I’ll hope XTZ one day will do active dsp speakers too.. the 99.25 maybe?
Produkt: EDGE A2-300
That small size is no indication of what this power amplifier is capable of. On the cooler side of neutral which is ok by me. That grip on the woofer of my Elacs is unheard of at this price range. Thank you XTZ for making high end sound available for the masses. Great after sales support too from XTZ, and a personal thank you to Tracy Zhang at XTZ HK for her patience and support.
Produkt: EDGE A2-300
The xtz edge a2-300 is a very good amp, so much power to such a little amp, neutral character, good bass control and definition, sweet enough and good resolution on the highs, only the mids are not exceptional, I will say a bit dry, but is acceptable in these price range, the imaging is exceptional, have a deep soundstage , not so large in width , but also depends on the speakers, one of the best characteristics its his excellent composure. A excelent buy and at this price I will say almost unbeatable.

Dopo un paio di mesi posso sentirmi di scrivere un parere su questo amplificatore,lo scopo e' quello di riprodurre musica liquida CD e vinile dunque ,premesso che l'edge 300 ha rimpiazzato un finale push pull a valvole di 6l6 da 20 watts e tuttora a pilotare il nuovo arrivato e' il mio fedele pre amplificatore a valvole made in Italy dela Lector M.L.A. Una piccola premessa va fatta, sono stato subito colpito da il fenomeno iniziale degli amplificatori in classe t qualche anno fa molto ben suonanti ma poco potenti poi sono passato al valvolare per notare questo prodotto in classe D ma dotato di una buonissima potenza quindi mi sono detto, voglio provare un finale di questo tipo,quasi privo di trasformatori.Bene prima di continuare devo dire che i diffusori sono una coppia di utah mod. 44 del 1976 Da 8 ohm e sono quelli che hanno ricevuto una seconda vita da questo finale di potenza che e' molto completo ....potente ,suono aperto e trasparente buonissimo con voci ,analitico dettagliato e velocissimo su alti toni bassi molto buoni e dinamici .La qualita' delle incisioni e dei file verra' esaltata se di buona qualita' m impietosamente castigata in caso contrario.un altro dettaglio sui diffusori che sono tre vie da libreria asospensione pneumatica con un bel woofer da 12 pollici .Unica cosa da fare e' trovare una buona regolazione del prezioso trimmer del volume per evitare di danneggiare le casse.ho ragggiunto il massimo da questa fortunata combinazione aggiungendo cavi di potenza Van Den Hull Hybrid e un buon cavo di qualita' tra pre e finale.Bene concludo dicendo che con una spesa ragionevole ho attuato un bellissimo cambiamento ricevendo anche i complimenti degli amici con i quali il sabato facciamo ascolti...bene grazie XTZ davvero un piccolo gioiello che vale molto molto....si quadagna ogni centesimo con un risultato davvero incredibile...preciso che ascolto Jazz Blues Afro Funky Reggae Rock e Fusion insomma un po' di tutto anche con vinile con il mio Technics SL 1900 .Spero di essere stato utile..Buon ascolto con XTZ Edge 300!!!
I have got this sub for a few months now. The room is over 25 square meters with a small kitchen and a hall (40 square meters counted together), so there is some place to move air. SUB12.17 plays in a 5.2 configuration. System is based on Polish loudspeakers (Pylon Audio, Diamond series), Yamaha (center and back) and NAD (front) amplifiers, and there is already one another subwoofer: Paradigm Seismic. The Paradigm is a little beast, with a very small, closed casing. But it's really powerful, Seismic it's not only an advertisement. So, the surrounding components are good quality. For now I have LFE signal through front speakers (they have very nice low end) and both subs. I had a bit of work to set subwoofers in the room, because of interference, but it's nothing special regarding a bit complicated system. When I compare Paradigm and XTZ both devices produces nearly same quality of bass, despite of absolutely different solutions (closed vs vented). XTZ is really fast, not muddy, also when REF is selected. Of course it goes really deep. For music I prefer REF, but for movies EQ2 with a bit of additional punch, just sounds better to me. What is really outstanding, XTZ has more tweaking options - standard vol, phase, cutoff knobs, eq presets and tuned vents. Movies and concerts are different, some of them with deep and loud bass line and some quite weak-sounding, and that's when XTZ comes in - fast switching or vents tuning and you're on the way. XTZ sub is really well made, details are outstanding (nice gloves, feels premium), and it sounds really good. I have to add that the manual is helpful, setup is easier, especially when you try to use EQ and vented ports.
My review after more than an year: The XTZ 10.17 Edge is a very well-made subwoofer especially in Gloss Black. The quality of the finish is simple superb. I have 2 with this finish for more than a year and they are still like new. Extremely resistant to wipe marks. This is not something we can say about many products with this type of finish. The brand support is also great! Always useful, fast and diligent. Regarding sound, I'm extremely happy with the subwoofers. I've heard a few subwoofers before buying this and after. I'm glad I choose to go with XTZ. For the price and size, I don't know nothing that comes close in terms of performance and adjustability. They sound great with movies and music. Fast, detailed and go really low even considering their 10” driver. The only downside I can think off… I had to do some work on my leaving room to eliminate a few rattles which were never apparent with my previous subwoofers😉. XTZ is a company that makes great products with great price-performance-quality ratio. The support is on the same level. I’m a very happy costumer.
