Review on 🔊 AIYIMA A05 TPA3221 Power Amplifier: 100W+100W Bluetooth QCC3034 APTX 2.0 HiFi Stereo Class D AMP for Passive Speaker by Heather Bell

- I've had this little gem for about two weeks now, play it about four hours a day and was very impressed from the first moment. - To be clear, I do NOT like writing product reviews, period. However, I am indebted to those who, like me, tirelessly seek real value in today's landscape of marketing noise for my consumer dollars. Suffice to say I can't think of a better deal than $79.99. This power amp sounds MUCH better than its specs suggest (impressive as they are). At very high levels, its power over the low-frequency acoustic stages never fails to impress me, and its slightly warm sound flirts with my nostalgia for tube amps of the past. Its signal-to-noise ratio and headroom suit everything from Bach's quietest passages to Deadmau5's stunning electric bass. I can't think of any sensible criticism given the price and would have no hesitation in recommending it to anyone looking for the best sound for their audio budget. Equipment used - Vintage Telefunken L250 4 ohm speakers - Proac Response One SC 8 ohm monitors - SoundArtist LS3/5a 11 ohm monitors, I had some trouble playing them at high volume, right channel volume dropped , but at normal close range they sounded just as nice as they did with the speakers mentioned above. I also used different types of preamps, the combination I liked the most was tube preamps. Sweet deep soundstage and very musical which made my speakers dance.
