BEZ T3B-5

Class A integrated power amplifier

If you have listened to any 300B amplifiers of BEZ, the T3B-5 model should definitely not be passed up.

It sounds amazing, rock solid bass, airy clean highs, huge soundstage that the features of 300B should have.

The circuit adopts alternating current(AC) to supply the filament of 300B. The design can max the power gain by 300B tube. It makes sure you get enough power for your speakers, meanwhile, lowest the hum level, guarantee the sounds quality.

2A3B is also available, only you need to do is to turn the AC switch from 5V(for 300B) to 2.5V(for 2A3B), and you can get another choice to enjoy your music. Hum level 2A3B is less than 2 mV when you are using 8Ω output, you can hardly detect any noise when your ears close to the speakers.

You’ll be astounded at the improvement in sound quality, dynamic range, meticulous transparency, completely demonstrate its high performance and analytical ability.

All point to point hand wiring feature always has better sounds than those amps using PCB.

The sound of the BEZ T3B-5 could also be better than amps which cost you 2-3 times from other factories.

Sounds is always our first target.
