Thoughts on a bunch of DACs (and why delta-sigma kinda sucks, just to get you to think about stuff) - Page 47

Looks like the MCD1100 uses the 9018 and the D100 uses the 9016.

Are there any actual discrete resistor ladder dacs in use these days?

Isn't the TotalDAC D1 Dual a resistor ladder?

Im convinced that is what the Yggy will be. The only other DAC I'm legitimately interested in, besides my M7 and the Yggy(aka is cheap enough) is one of the Lampizator dacs, like the Gen 4 level 4 dac. Purrin you should check one of those out :P

I doubt the Yggy will be a resistor ladder at the projected price of ~$1800-1900. The labor to make one must be ridiculous, mostly in the testing of the resistors and matching them.

I was told here that the msb is one. perhaps that accounts for the price among other things. it is insane at pcm. I have a $1,500 creation of mine that is better at dsd. that is no surprise since mine is sigma delta.

I love the MSB DACs, but I am extremely suspicious of the MSB black golden box modules. Do you guys remember the "discrete" Ultra Analog DAC modules from yesteryear? I've heard several DACs using them such as the Moth HyperDACs, Classe, maybe a few others.

 

Well after a few people cracked these $$$ Ultra Analog suckers open, it turns out they really had BB PCM63 chips inside them. Hahaha. For all we know, the MSB modules could have a bunch of cherry picked PCM1704-Ks inside.

 

Again, doesn't mean I wouldn't get an MSB DAC if I had the cash to blow. And the the TOTAL DAC stuff is crazy legit.

Marv, sign me up for your TotalDAC D1 Dual loaner program.

purrin, if that was the case I would be pretty unhappy. I mean it sounds super but it wouldn't be worth the premium then. I was wondering how the diamond dac iv select is "80 bits". I assume that is their sharc dsp but what exactly does it do in that sucker? the inputs obviously only go to 32 bits. is the audio converted to 80 bits or something? sort of like what the forthcoming ps audio and nad m51 do. I have no idea whatever they do it obviously works.

Me too, given that I believe it's impossible today to find a discrete resistor-based ladder DAC below €6000 these days.

 

What are the alternative ? I've heard of "FPGA" processors, but I believe those can only be used to upsample the signal with a proprietary filter to avoid using the DAC chip embedded converter, am I right ? At one end you'll still need a DA chip of some sort ?

PS Audio PWD II now $1,995 new at their site.

 

Use as is now, then get upgrade kit for $2,995 or trade in or get $2,000 credit later.

The TotalDACs look awesome, even just down to the internal boards. I want to listen to one a lot, but they're so pricey! :( Same goes for the Phasure NOS1 and MSB DACs.

I've read a little more and I believe I now understand the ways in which it could be used... Apparently the new PerfectWave DAC is a FPGA that converts and upsamples everything to DSD and then sends the signal to a discrete D/A 1bit board, isn't it ?

 

Perhaps that's also what Schiit is going to do. I can't really see any other way to make a DAC without using a dedicated integrated chip that costs less than usual discrete ladder DACs.

 

Obviously please forget everything I just wrote if it's sheer idiocy combined with utmost ignorance.

He sold it. I still give him crap about it to this day "So where's that POS DAC?" He then tells to F off.

It's either your UD501 a defect one, or we have very different music taste. And to be honesty, no matter how much you don't like the TEAC, claim it as POS made your whole thread meaningless to me.

Thanks anyway for your effort. I'm going back to enjoy the POS.

Purrin,

 

  We did some ABX tests in chile  with the  SE outputs of the following combos:

 

1. Master 7  + Master 8

2. NFB-1.32 + NFB-6

3. ODAC+O2

 

We couldn't find diference at all with this tiny ABX box, is there something that could be happening that I can't tell appart any of them?

 

I'm sure there are diferences while listening to them separately, but I can't measure it
