I found this forum from my curiosity of the Dayton Audio HTA200 tube amp. I've been wanting to check out the new inexpensive tube amps that are making so much noise, so I decided to test two different hybrid tube amps, the AIYIMA T9 PRO 200W Integrated Bluetooth Digital Class D 2.0/2.1 Channel Hybrid Tube Amplifier, and the Dayton Audio HTA200 200W Integrated Bluetooth Class A/B 2.0/2.1.. Upgraded Version of AIYIMA T9 Pro Tube Amplifier:The circuit design is upgraded,Using a better Qualcomm Bluetooth 5.1 version chip,fast and stable;Add the new dial layout display is more convenient;Add sensitivity adjustment of VU meter on the bottom of T9 Pro power amplifier;Remote control updated .
The Aiyima T9 Pro is an outstanding product that delivers incredible sound quality and versatility. The build quality is solid, and its performance is well above expectations for its price range. The integrated tube preamp adds a warm, rich tone to the audio, making it a perfect addition to any home audio system... Aiyima redesigned the tone controls on the Pro model to only be operational with the remote, removing the knobs from the front of the unit as seen on the original T9. This was an interesting choice because remotes are easy to lose and with the Pro model, once it's gone missing, you won't be able to adjust treble and bass via knobs on the front of the unit like you could the original model.
