Stan's New Dac - any reviews yet?

[kbuech]

Kurt,

Very interesting to hear the opinion of someone whose is using the TC-7520 in conjunction with powerful and quality amplification. Are you using anything special in the way of power sources for the TC-7520, or just the standard power plugs supplied by Mr.B?

I'm using the stock power-supply provided by Stan for US 120 V.

However,

These are plugged into Furman power-conditioners: 2 with state-of the art filtering plus power factor correction, 1 with the same filtering, and one basic Furman unit.

Hello,

does anyone know if it is possible to connect an ipod via USB to the TC-7520? Does one need a special docking station?

thanks

You'll only get analogue out from the iPod. You'll need the Wadia docking station.

One question I frequently get asked is whether it is possible to adjust the volume of the TC-7520 from the PC. What I have found out is that you can adjust the volume from within MediaMonkey if you are listening to the TC-7520 via USB.

The direct digital out from the iPod is locked - a licence fee has to be paid by a manufacturer to unlock and use the direct digital out.

There is open source firmware that can be loaded onto an iPod and I have heard those software coders may be working on accessing the direct digital out - it does, however mean that you would be, in effect, running a different Operation System in the iPod. Not iTunes, but something else which would work with open source codecs like FLAC and OGG.

Not a review, I got my TC-7520 today and my initial listening is very promising, even without proper burning in.

I just wanted to say thanks to Stanley and to others that's considering this DAC, "yer in for a treat", as someone told me before I bought it

It's 2am and I badly need sleep but this dac keeps me here for just 'one more song'

Will have some Burr Brown OPA627's shortly to replace the 5532's, will let you all know how they sound.

The OPA627 is not a direct replacement for the 5532!
Try the OPA2134 or LM4562.

I would have thought Dual 627's per socket would be ok?

I have some LM4562's kicking around somewhere to test too, always thought the 5532 and the 4562 were very close in terms of quality, how did they sound to your ears Stan? Never heard the 2134 though.

The LM4562 is far better than the 5532 in performance. Higher slew rate and lower distortion. Mind you, the 5532 situated towards the right side of the PCB (looking at it from the front), is probably left well alone.
