I bought mine online from "ThinkGeek" in USA two years ago.
Google ThinkGeek or T-amp to look for the link. US$30- a piece + shipping will be about HK$500-.
Will arrive within a week by DHL or UPS.

i have never been a fan of cap upgrade, i did some before but honestly i could not listen to all the difference. May be each time i swap out a cap the souond is different but not necessarily towards a better directon. Just different.

But this time, i have the two input caps on my Charlize (triapath 2020 based amp). Orignally I have a highly praised budget caps 2.2uf Obbligato copper tube in place, and recently after a lot of internet research, I took the decision to purcahse two Mundorf cap supreme silver/oil to try, and to see if they are really that good, and to also see if I can really tell the difference. My friend helped me restructure the wiring a bit so that I can swap different caps for comparison.

I must say...simply breath taking. I like Charlize for the cheap price and good driving power. The bass has always been good from Charlize, but since I use small watt tube amp like Colin 5687 single stage and 71a direct coupled amp, I feel, in comparison, the charlise tripath amp's high frequency is not detailed and refined enough. All those nice harmonics, details and nuances from violin solo are missing a bit. I got lots of these from my 71a triode amp. I always want an amp that has the refinement of single ended tube amp but the power of class-t...now i got it.

With about 20 hours break in on the mcap silver/oil, the amp is already performing in another level of refinement. It sounds better than all the 300b amp I have listened to (sorry, i have not listened to all, but some), and now the high level freq performance is very very clsoe to my single stage Colin 5687 tube amp and 71a tube amp. The charlize sounds more robust and massive than the tiny triode singled end amp.

The mcap surely cost more than the Charlize itself, but much cheaper than a pair of NOS triode power tubes. This is one of the most encouraging experience of electronic components I hvae had in years. I dont' normally hear sublte difference between cabling changes etc. But I can hear the mcap now is a very obvious improvment.

Very interesting in deed.

please note:
for models (Tripath) higher than 100w (4 ohm), it employs MOSFET at the output stage

kevintsang hing,

Output max - Maximum output, close to maximum recomended voltage / minimum impedance load. At this output, you can assume the THD+N is high, >>1%. At below 60% of this power level, the THD+N is well below 0.1%.
Chip - The chip this amp is based on
Br - If it is possible to bridge the outputs
SMT - If the kit is built with (small) surface mount components.
PS - If there is a power supply on the PCB (the transformer is in no case on the PCB)
Supply - External power supply needed
Max DC - Absolute maximum supply voltage
WxD - Board width and depth in millimeters.

welborne hing,

is it this one ??


Amplifier based on the Tripath TK2350 chipset

The AMP2 is a 2 channel (stereo) power amplifier module operating in switch mode. It is capable of delivering some serious power; in its basic version 2x300W into 4 ohms with a +/-45W power supply. The sound quality is exellent. The amplifier is sold either as clean PCBs or in kits with components that you assemble yourself.

****WAITING FOR YOUR COMMENT PLS.

i bought the assembled board for USD90 that has the special air core coil.

You still need to make a box, solder on the plugs, rca, speaker plugs and power socket, and that is.

oh, you need to put in a volume pot too.

you can check here www.diyparadise.com

Hi welborne,
How much you bought the TA-2020 T-amp from Charlize, is it comes with outer case or not
and the adaptor is in 110V or 220V.

Thanks
DY
