This is a review of the Aiyima T9 PRO integrated amplifier with tube stage. I was looking around the internet and saw that most integrated amps nowadays have built in digital to analog converters which I believe is excellent for music lovers. In searching for something new I found a class-D amplifier with tubes in the mix. Specifically Jan5725 tubes. Of which are included with this amplifier.

Since this amplifier is based on the Texas Instruments TPA3250 it has enough power to power my speakers with ease. For that reason is why I purchased this amplifier. Another reason why I decided to dabble with this amplifier is because I was in need of a 24bit 192khz USB DAC and this has one built into it, along with toslink and coax at 24bit 192khz. In addition to that it has Bluetooth audio and an RCA input.

It seems from looking at it, the small size of it makes for an ideal desktop amplifier if one has speakers near their computer. I use this instead as an amplifier in my system for daily listening. Sitting right where I would put an integrated amplifier of much larger size.

After a couple of days listening to this particular interesting integrated I decided to keep it.

Listening to Brian Eno "Music for airports" CD quality I noticed acceptable sound. The music seems to like added texture to it so I managed to pull back the treble by 3 notch settings and pull in the bass by three notch settings. This removed the revealing analytical sound of the TPA3250 and increased the body and texture of the album. This turned the music into great background music to have on.

I then put on The Doors "The Soft Parade" Hi-Res album via the USB input with the treble and bass at flat response where there was no emphasis in bass or treble and I thought the sound to be excellent for the price. I couldn't believe it until I heard it as to what it is. High-Res sounds way better than CD quality.

I believe that this amplifier revealing the differences between recording quality are reason alone for listening to this amplifier to see what it can do.
