The sound of the T3 is difficult to describe. While superbly balanced throughout the audio frequency range, it is the ability of the T3 to accurately resolve complex harmonics that is most impressive to me. As an example, instruments such as oboe, bagpipe, etc sound incredibly lifelike.
I also use several recordings that have ocean sounds and applause when evaluating amps, both of which are difficult for many amplifiers to accurately reproduce. The T3 is remarkable in this respect. Everything I threw at it was reproduced in a very lifelike, realistic manner.
The soundstage and imaging is superior to the T4, as well as to many amps costing hundreds of dollars more.
I continue to me amazed at the level of performance possible from an amplifier that is only slightly larger than an aspirin tin!
The overall performance of the T3 certainly belies its size as well as cost.
There is no question in my mind that the T3 represents the best performance for the least money of anything currently available. Performance wise, it would still be a bargain at twice the cost!
