CDM2Pro Metronome Buffalo i2s connections schematic

Hi,

Member Wobbly send me this schematic for connecting the CDM2Pro via i2s with metronome and Buffalo.

Wobbly and I think that this can be of use for you guy's who want to try this, have a look.

Thanks Wobbly 😀

Placed my order. Funnily enough they're still on sale, so there must a pretty big herd of Buffalo in the making.

Really looking forward to it as a Christmas present when I eventually get it, but I'll be using the SPDIF output of a E-mu 1212m to drive it (I think it's a transformer coupled output capable of AES or SPDIF output). Given that my source is a computer, could I be doing better than that?

Any word on when a USB adaptor that will pass 24/96 will be available? 😀

We have wanted it for a long time. The problem is there are not many chips that can do it. In fact there is only one easy to use chip I know of. 🙂

http://www.cmedia.com.tw/?q=en/USB/cm6620

But we can't seem to obtain the part or even a datasheet... 🙁

If someone knows how to get them I would be grateful to know.

If I could get these I would get a module done in no time. 🙂

Cheers!

Buffalo/CounterPoint/Placid Interconnect, ver 1.0
Here something I put together, an interconnect diagram of all PCB to get a full blast Buffalo DAC, using the upcoming Counterpoint I/V converter and the Placid Shunt Regulator. I'll do one for the IVY as well.

It includes almost all possible options:
CS8416 MUX PCB; Allows 4 inputs, on my schematic BNC SPDIF, AES/EBU, Toslink and USB. It sends I2S interface directly to the Buffalo for the lowest jitter configuration as suggested in the thread. But I also connected the SPDIF if needed.
USB Receiver DAC (with optional headphone jack output)
TOSLINK Module
Buffalo DAC with optional Volumite PCB volume control
LCDPS Dual Supply and its 2X9V Transfo
Pair of Placid Shunt Regulators with their 2X15V Transfo
Pair of Counterpoint I/V Converter (PCB BETA wiring, since I don't know the exact final Counterpoint version and interconnect)
AC input suggestion

I was a little confused at first with all the modules offered and their different connection options, connectors marking, etc.

This diagram explains everything, at least to me 😀

Hope it can be useful to others as well.

Buffalo DAC + IVY + MUX + LCBPS + LCDPS + Transformers are ordered – to be shipped sometime next month.

I'm going to order a Metal Enclosure with appropriate holes and opening punched, which I'd like to get before getting the modules from Twisted Pear.

Also, I have some Mods in mind, especially concerning further cleaning and "ironing" the various DCs from the PSUs. Yes, I know, some will argue that the setup works great as it is and that no Mods are likely to give any benefits I may actually hear. To those possible arguments, I have a very simple reply. Even a great-sounding DAC can possibly sound even better (and not all differences in sound, like the sound-stage, are measurable). From past experience of dealing with audio gear, there is no doubt and no question that the cleaner the DC supply is – the better the system sounds.

For the above, I'd like to have the BOMs of all modules ASAP. The BOMs I still don't have are for the CS8416 Mux, the LCBPS and the LCDPS. I emailed Twisted Pear last week, but was not replied yet. I believe those guys are really busy. Can anyone help me, please, with those BOMs?

Also, until the Placid PSU will be available, my present idea of the most clean DCs I can possibly get from the present PSUs (apart from careful wiring and EMI/RFI isolation) is to have 2 pairs of PSUs in tandem – 2 LCBPS in tandem and 2 LCDPS in tandem – of course, omitting unnecessary duplicates, like rectifier bridge and adding some HF/RF filtering. Any ideas about that?

Gentlemen,

I just finished my implementation of MUX receiver ahead of Buffalo.

I am very happy with the results - all crackling seems now to be gone and the sound is significantly better with a little more extreme fine level detail and more natural sound compared with the SPDIF direct i/p

Already before the addition of the MUX I had taken extensive & significant measures to reduce noise in all power supplies and also taken much care to keep the different elements individually screened - some evidence of both in picture.

I'm still using voltage output via S&B 102 Mk 3 transformers ( which I think sound better out of their cans ).

Next I will resume comparisons of USB from Sony Vaio notebook V SPDIF from pioneers DV-400V on CD replay.

In the meantime I am feeling very satisfied how this project has worked out.

Thanks to Russ & Brian and all other sources of advice.

cheers

mike

I certainly would not argue with you on the power supply points.

The BOM for the MUX is on the site now (slipped it in the other day). I will create one for the power supplies this evening.

I thank you for the fine diagrams. Probably you could draw another placid just for the L+R analog (AVCC) supply of the buffalo. Probably we remove the opamp there. Then one side of the LCDPS could be used just for the digital supply of the buffalo, the other one for MUX, Toshlink and Volumite.
