It uses the same components, except for input power supply, right ?
Thank you.

v2 is parallel circuit so will be a little hotter than v1, so if you don't need it for 4 ohm speaker, v1 is a little more suitable for 8ohm.

What is the better approach soundwise - V1.1B implementing one STA508 stereo output transistor or V2.0 with one STA505 for each channel?

I have already SURE ELECTRONICS tc2000 + tp2050 two channel board with passive cooling. I would like to have an even better implementation of these Tripath chips, if possible, and with all other proven tweaks implemented.

I think both v1 and v2 will be ok for you if don't consider the load impendance and powe supply.

Nice, that should work well, I'm quite tempted to try one now.

So... finally come to the end of this thread. A nice little 3 hour story

Your amps look really nice hifimediy and cudos for you in-depth replies and corrections on request.

I have alot of T-amps (sure 2050, 2024 - 41hz amp32, amp9(B), amp10) and I really love the sound, especially from the well implemented ones like the 41hz amps.

I have long been dreaming of a 5 channel or 7 channel class T surround amp for my OPPO BDP-83, but should I buy 3-4 of your v2 modules or wait for an all digital solution like DDX?

I haven't quite figured out yet whether all digital is the ultimate solution (like going from VGA to DVI/HDMI). Is all digital (power dac) the pinnacle of quality compared to a nice DAC solution like the CS4397 to a 2050/3020 T-amp or can there still be issues in a ddx amp that will make it come in 2nd vs. the T-amp solution?

What do you think?

For multi-channel solution, I think you'd better consider DDX system(means a new project after AMu320 2.1channel). But if you have a good DAC already, you can also consider 3~4 pcs of AMT2050 boards to use together.

The CS DAC in the oppo is very good, also for multichannel.

Do you have any comments on this "I haven't quite figured out yet whether all digital is the ultimate solution (like going from VGA to DVI/HDMI).

Or comments from the rest of you peeping toms following the thread

Just to let you know : I have ordered the v2 PCB kit, RCA, HP connectors and a Meanwell 350-27 .
I just can't wait trying all of this
Do you have advises for the chassis/box ?

I plan to try Obbligato condo, and ALPS black beauty potentiometer.
I'll work on a ventirad solution, heat is a real problem.

Thank you !
Regards from France,

Excellent and good job !
I would need the same kinf of box/chassis, perhaps not so high though

I advise you to take off the actuall pot, put a new one directly on the box and wire it to the PCB. Like this you can try other pots, and I promise that a good pot changes really alot ...

An ALPS blue would be better, an ALPS black beauty even more, a Dact-like, TKD, Elma, Seiden ...

Just check here :
potentiometers, switches and attenuators homepage

Do you have ebay links where to buy those chassis/boxes ?
Is it aluminium ?

Thank you,
Regards

PS: hey, I love cardboard

Any experiences with Power Supplies or similar?

The switching frequency for the meanwell is quite close to the auible band in my oppinion so any comments on PSU choice is appreciated .
