Icarium Posted September 6, 2007 Report Share Posted September 6, 2007 http://picasaweb.google.com/asebastian2/DoubleCrown/photo#5107114672554852322 So pretty! These are the ultra rare and highly acclaimed double crown version of the 20 year old R2R non-OS Phillips TDA1541A chip. Haven't been tested by my DAC builder to see if they are legit ;p But hopefully they are! They use this chip (only 1 or 2 though) in the highest end Zanden dac and various old school players like the Marantz CD-7. Apparently crazies in Japan build dacs with 32-64 of these chips per channel. Very pricey at $100-$150 if you can find them ;p Asebastian sourced them for me and is planning on sticking them in a modified version of this dac: http://www.ecdesigns.nl/dacs/di8m/di8m.html http://www.diyaudio.com/forums/showthread.php?threadid=79452 in a custom chassis ;p Excited! But sadly this project will have to be sidelined with the purchase of my transport and lack of funds Ohwell at least I have the pretty chips... been wanting something with them in it forever. But finding a Marantz cd-7 is tough (It even has a digital input!). Quote Link to comment Share on other sites More sharing options...

Icarium Posted September 6, 2007 Author Report Share Posted September 6, 2007 Yeah I don't doubt that they are vastly over priced and aren't the best possible chip. In fact Filburt told me he prefers some other R2R chip that I can't remember off the top of my head. Still, I seem to go for the overrated products and I kind of wanted to hear for myself how it sounds. Quote Link to comment Share on other sites More sharing options...

Icarium Posted September 6, 2007 Author Report Share Posted September 6, 2007 What can I say I hate money. If you want some from me you just have to slap the words "Rare"/"Best" whatever on it and I'll cough up the bank. Quote Link to comment Share on other sites More sharing options...

I have the PCM1700 in my CD player, not quite as a good as it's only an 18-bit chip as opposed to the 20 & 24 bits of the others. Still pretty happy with it though.

Icarium Posted September 6, 2007 Author Report Share Posted September 6, 2007 Yeah I think the PCM63 is the one that Filburt likes best. It's cool. Will still sound good. Now I just have to get the deal worked out for wood puck feet for the DAC made from a mix of Noah's Ark and the True Cross. Ah, sonic bliss.

DigiPete Posted September 6, 2007 Report Share Posted September 6, 2007 add to that the top BB 1792 and slightly lower 1796 Quote Link to comment Share on other sites More sharing options...
tkam Posted September 6, 2007 Report Share Posted September 6, 2007 I tend to prefer the pcm1704 but out of the current delta-sigma dacs i like the AKM4396 the best followed by the pcm1792/4/6 Quote Link to comment Share on other sites More sharing options...

Do the extra bits help when you're decoding 16 bit data? Quote Link to comment Share on other sites More sharing options...

DigiPete Posted September 6, 2007 Report Share Posted September 6, 2007 Do the extra bits help when you're decoding 16 bit data? They do if you have a DSP that upsamples the data to 24 bit... and even better... to 96khz Quote Link to comment Share on other sites More sharing options...

I am definitely going to get them in my other source when I have the money for an APL mod. Still I am very curious to see if the retarded premium I'm paying on the double crown can equal or beat the AKM chips in redbook. Quote Link to comment Share on other sites More sharing options...

aerius Posted September 6, 2007 Report Share Posted September 6, 2007 Do the extra bits help when you're decoding 16 bit data? The short answer is yes, it does help. The long answer involves a lot of math which I don't understand anymore, as I've been out of university too long and my Calculus is pretty damn rusty.

Icarium Posted September 6, 2007 Author Report Share Posted September 6, 2007 If you like that NOS sound then it might just. Me, not such a fan. I have a Wavelength Audio Cosine dac right now. i forget which chip it is but Filburt might remember he took a look inside. It's a great sounding DAC owns the FUCK out of the Monarchy M24 I used to have. The improvements on detail/tone are subtle and slight, but the very fact that it has like 3x the soundstage was a big deal to me. the Monarchy was remably narrow.

Nanoha Posted September 6, 2007 Report Share Posted September 6, 2007 The TDA1541 hype is pure bullshit. Yeah I don't doubt that they are vastly over priced and aren't the best possible chip. In fact Filburt told me he prefers some other R2R chip that I can't remember off the top of my head. Still, I seem to go for the overrated products and I kind of wanted to hear for myself how it sounds. I'm guessing he prefers many other chips over the TDA1541.
