- I wanted - probably as everyone - to try the T-Amp. At first I bougth
the original T-Amp to play around with that toy, but wasn't very
But I chose to give it another chance and bought an assembled pcb at ebay. It was the TA-2021B pcb from art0 and sounded much better than the original T-Amp.
After struggling some time with the power supply ->
1st try was a digital switching unit, that wasn't really cheap - but was real crap (I had high frequency noise in the speakers).
try was a trannie from a halogen bulb - but for that I had to build in
a rectifier circuit, which I first wanted to avoid. But ok, done so -
and it was ok.
3rd try - and that's the current setup - an IBM
Notebook PSU with 16V= through the rectifier circuit. I can hear no
real difference to the 2nd try, but it's a bit smaller.
Ok - How does it sound ?
I think really good as long as you use adequate speakers. It was no good match to La Obertura but a VEEEeeeRY good match to La Cigarra.
So - out of the reason that I dismantled the towarišč solcnekot
to rebuild it in another chassis - I'm now listening to Herr_T for more than a year - and
- what should I say - it can't really match up to the towarišč,
but I'm happy and don't miss anything really important.
For the price this "toy" is a bargain - Don't miss to give it a try - Normally you shouldn't regret it.
