Probably this is already stale news but here’s my own experience with the T-amp kit:
I helped my colleague (
one of the guys I managed to poison) to solder an el-cheapo RM3.00 volume potentiometer to the T-amp using JP’s 40sen per metre multistrands wire and plugged it into and bypassing the built-in amp of a JVC UX-5000 midi compo in my office.
When the sound comes about after ridding off some initial hums, viola, it sang so well. I had never heard my JVC midi to sound so complete before – the clarity, details, tone of instruments, macro dynamics, decay, the emotion factor, PRaT and not forgetting the bass I am now hearing through the 3” paper-cone speakers are awesome. I was also able to notice the recording of a particular CD was made from aged master tape, yes, the T-amp is that transparent! And all these from a RM55 kit amp? Hard to believe but it’s definitely true. So much so, when we finally took out the T-amp from the JVC midi, it was rendered not listenable anymore – blur by comparison.
The day proceeded with both guys I poisoned calling /sms-ing me at my mobile even at wee hours of the night. Boy, both are badly poisoned and excited by the unbelievable sound they are getting from their T-amps.
A finding by my friend (
the other guy poisoned by me) – he has been following comments made by forumers of this thread and he experimented with some input caps himself before finally settled for my extra pieces of
made-in-Portugal Vishay 2.2uF 63V polypropylene caps. He noticed that the slight pop sound to loudspeakers after changing input caps are still there even with these caps and thought perhaps the offending small caps which came standard with the T-amp kit are more to discharge off the extra charge stored in the caps and so to take care of pop sound rather than to enhance the sound quality. He felt with Vishay 2.2uF, the highs are more apparent, sweeter-sounding and more ‘flesh’ to vocals. Hmmm, ……
As for my own T-amp, I shall be fixing a 24-steps 50K ohm discreet attenuator to it and commence work after office today
after having double-confirmed the input/output soldering points to it. And at rate things are progressing, I reckon I will spend my entire weekend with my T-amp.
