Electronics engineer's review will be coming soon (tm) As a consumer, the A70 just works. It is a great amplifier with some really cool features I never knew I needed. As far as I can tell, it meets or exceeds all its specifications for TDP, power output etc. I will be evaluating this in more detail under different loads at a future date so for now I will cover more of the cool features: 1. XLR is a nice to have. I don't personally have any in my setup but occasionally I have used it for odd or specific setups. 2. The +6db is REALLY nice. Some audio sources are really quiet. The worst offender is an LG TV that automatically drops the volume every 30 minutes if you set it above a certain level in the UI. The trouble is, the TV doesn't actually know how loud the room is so this may be going from a comfortable volume to nearly silent. The +6db allows you to get the full range out if this amp with such sources. 3. The built in crossover is cool. Not used as I have a full equalizer for room calibration but I can think of times it would be useful. 4. The 12V trigger is awesome! I cannot wait to build a custom controller for this that allows it to be switched on and off with the rest of my setup to allow for energy savings. I really only have two gripes: 1. AIYIMA already has a product with the name "A70" which could be confusing. They also advertise this as being used for 7.1 surround setups, but having 8 of this seems like it would require excessive tinkering to get a room to sound good compared to an all-in-one receiver that is programmable.

Come al solito ho aspettato un pò prima di recensire. Che dire,lo sto usando con l'impianto HT in mono su un subwoofer con 2 altoparlanti 4 ohm da 25 cm messi in parallelo tra loro. L'apparecchietto,per le dimensioni, se la cava egregiamente: pilota il subwoofer alla grande,senza minimamente riscaldare. Si, lo consiglio!

Manque cruel de punch. Incapable d'alimenter un sub 12'. J'ai dû le retourner. Sinon objet joli.

Das ist die Zukunft der TPA3255 Amps, diese Endstufen haben keine der Eigenheiten der einfacheren Konstruktionen, sie sind extrem sauber im Klang, arbeiten mit sehr verschiedenen Lautsprechern hervorragend zusammen, und haben wirklich Leistung ohne Ende. Auch die Lautstärke auf beiden Endstufen gleich einzustellen, ohne sie voll aufdrehen zu müssen, erwies sich als viel problemloser als gedacht, erstens sind die Regler gerastert, man kann also mitzählen, zweitens sind die Lautstärkesprünge pro Raster genau so dosiert, das man sie gut hören kann. Sie werden kaum warm, weniger als jeder Transitorverstärker, sind komplett leise, also weder Rauschen noch Knacken beim Einschalten, noch sonst irgendwas. Mitgeliefert werden richtig gute 48V/5A GaN Netzteile, eine neue Technologie, die kosten einzeln schon um die 50 €. Eine gewisse Möglichkeit den Sound zu beeinflussen hat man mit der Wahl der Eingänge, RCA ist dynamisch etwas limitierter, und sanfter, XLR ist wirklich SO sauber, das man denkt die Anlage wäre kaputt wenn eine Pause in der Musik ist, so ruckartig passieren die Klangereignisse, ohne jede Vorwarnung. PS: die ersten paar Stunden klangen sie noch etwas scharf, das war jetzt am 2. Tag weg
