TDA1541a S2

[Rotellian]

OK, ive seen a s2 for sale. However, the picture that goes with it is identical to the pic posted by peter daniel - so is it genuine?

[Peter Daniel]

I got 2 pcs of TDA1541 S2 from Elib, who adverised them here on a forum.

He was generous enough to send them to me before I paid him, just to check them out. I was pretty busy recently and didn't have my system set properly do do that, but hopefuly today, I will try them out.

From a visual inspection, they look real. The pic I posted, was the one that original seller sent to me.

I did some listening today. I was checking the chips in my Marantz CD94. The S2 seems to be a real deal, as it sounds different than a regular version and S1. It has very silky like trebles with good resolution and detail. Sometimes it seems like the highs are actually too soft, but it's very pleasing and not fatiguing at all. The regular version of a DAC, in the current setup (OPA627 at the output, no filtering) is too harsh sounding and I wouldn't hesitate even for a moment and prefer outboard TDA1543 DAC. I also checked S1 version and it is less harsh sounding than no crown DAC, but shares similar sonic signature (just a bit more nicer sounding). But S2 seems to be something else. It is a bit mellow, but again very good resolution and detail, revealing the sounds I might not hear before. I think I like it, even in the current application (slightly modified Marantz circuit), and can only imagine the performance it may bring when more care and attention is used with a better implementation.

It's almost like comparing generic metal film resistors and Vishays.

thanks, Peter, it's so good that you like it.

for those intereted in this chip:
i still have quite a number of the chips for sale, the price is:
75 USD/pc + shiping
68 USD for 10+, plus shipment.

i also have cs8412cp's in stock.
are there anyone interested in a 1541 dac project? if someone can design a pcb i think i can supply them quite cheaply, maybe at $2 or so.

How much would it cost a CS8412?
And a "regular" 1541A ?

Cheers

PS Stefano, in case we might share shipping costs
