New finished sure TK2050

These are on ebay now for <$60 shipped. Don't think it comes with power supply though.

Anyone tried one? Seems like a reasonable deal.

There has been much discussion on these boards. Several DIY-ers have made interesting mods to change input and/or output side of the board. Do a search and you will find some amazing results for this neat little amp that can hold it's own.

I'm not asking about the boards. I'm asking about the finished product they are selling and how it stands up as a finished product.

I will be looking at one later today (or tomorrow for Western hemisphere - it's 7:30AM on the 10th here).

I'm also very interested by this one, price is good...

Hello,

The electronic volume control makes this amp unusable. Distorted at low setting of the amplifier extreme. An ordinary potentiometer would have made more sense. Thus, this amplifier can be used only as a power amp.

In addition, the electrical phase is rotated by 180 degrees. One speaker cable to a port had to be reversed on the board to play with the speaker in phase.

Both are unforgivable error. Quality control by Sure-Eletronic seems to be deficient.

Sonically much better alternative is the SMSL SA-50 or Dayton DTA-100.

Also Hifimediy TK2050 T2 amplifier sounds significantly better.

Greeting

Michael

Well, that settles that. Still holding out for Hifimediy T3 or T3_v2 to be for sale I think.
Thanks for reporting in on this thing.

Neomatth · 15th September 2011, 09:02 PM

Yes, thank you for the info...

I have sent an email to Sure on the volume control issue and they replied on Tuesday (GMT +8) that they will look into it. Well, today is the deadline and if I don't get a satisfactory reply then I'll be sharing what I know with the rest of the internet.

(Sneak preview: "Distorted" does not give the full picture of the problem. Although technically it is distortion.)

Again, thank for the info about the sure.

I see that for you the smsl SA50 is far better, but apparently it uses a TDA7492 which doesn't seem to be appreciated in some threads...

Distortion Tests - HifimeDIY T2 / LJM L20D / SURE TDA7498

I know it's the TDA7498 in this one, but they seem pretty close.

Actually, i have an smsl dac and amplifier on my main system and i'm pretty happy with them, so the SA50 could be the next improvement...

Could you tell us more about it ?

Thank !
