Hi Martin,

It does sound very good indeed.

I have a Sony CDP 227ESD (Dual TDA1541), a Marantz CD-17 (TDA1547) and a couple of other DACS which I bought off Ebay. I also have a heavily modified Musical Fidelity X-ACT.

And to my ears I rate them as follows:

1) Sony 227ESD
2) This TDA1541 DAC
3) Marantz CD-17

There's little to choose between the other DACS, and it may even be that my system (or my ears!!) are not good enough to tell any further differences.

But this TDA1541 DAC is certainly very detailed and warm sounding.

By the way, the rest of my system is a Sony TA-FB940R Amp and Dynaudio 52 speakers. I have also tried other amps (pre power combos etc.).

Tony.

I got a pair of toroidals from Rapid electronics.

Rapid | Distributors of electronic components, electrical products and educational supplies

88-3409 MINI OPEN TOROID 7.0VA 15V+15V 0.233A RC EACH £8.56
88-3406 MINI OPEN TOROID 7.0VA 7V+7V 0.500A(RC) EACH £8.56

These are nice and compact (approx 50mm diameter)

I have attached a pic of my DAC wth transformers.

So cute the toroid transformer ^_^

Why is this design and I are so similar?

This is my design：

An externally hosted image should be here but it was not working when we last tested it.

statement:This 1541 kit is a open source project from ming9002，http://bbs.hifidiy.net/viewthread.php?tid=245788&extra=&page=1
I must apologize to ming9002 for sale this kit without his permission.This kit was made by luzhu,not by bbp.
抄袭明兄的板子确实有错。事后和明兄沟通过，他同意我继续出售手头上多做的套件，只不过为了减少影响，没有在国内销售。希望明兄和各位兄弟原谅，只此一次，下不为例。

It does’t matter.

The circuit board looks like it is from hifidiy.net ....
Any connections to that site ?

Hi,
I've just started my modified version of the kit
It uses a TDA1541S1 and BurrBrown OPA627

The floating wire from the SAA7220 to the DAC are a temporary NOS conversion, I'm preparing a OS/NOS option switch

The sound is perfect, deep and really punchy

There's only a little 'mains hum' you can hear by pushing the power amp to its maximum, I guess this is inducted from the proximity of the opamps and the PSU
I'll try a mod

Can i still order one?

bump for a little deal >_<

O.K., now that i've other things out of the way are there any left?

I'm currently having some problems with mine, as documented here.

But when it worked, it was good.
