Very true about cables.

"The DS is about 3dB lower in output than many CD players or DACs. Most of us have much more than that amount of headroom so it's not usually a problem.  The thing is that the PWD is hotter than many DACs so some people have systems with no preamp that work with the PWD but perhaps not without a preamp with the DS.  (BTW other people have systems for which the PWD has too high of output level and are happy that the DS has a lower output level.)"

@ Kana813 ~ thanks for that!

After reading I would assume that one would get better performance from the DS using a Preamp, but  unfortunately if someone wants to go "balanced" then we have to look outside Decware at this point.  McGowan uses the somewhat expensive Balanced preamp from Aesthetix called the Calypso.  The Wyred4Sound STP-SE seems to be fully balanced at $1999 ... that may make a nice pairing.

beowulf:

Ted Smith posted these specs for the DS outputs on the PS Audio forum:

Balanced: 2.8V RMS or 8V p-p 300 Ohms
Unbalanced: 1.4V RMS or 4V p-p 150 Ohms

LR's ZMA needs 2.0V on the SE inputs, I don't see any specs for the optional balanced inputs.

I'm going to try a DS with my REF 75, which needs 1.4V on it's balanced inputs.

A few of the Decware amps have options for XLR inputs, but I think it's fair to say that they were designed to be SE.  

I remember asking Steve about the voltage needed for the ZMA to come to full volume with the balanced inputs, and it is also 2V.  

In my system, with the ZMA, I prefer the lower voltage RCA inputs (~2.8V) running the PS Audio PWD direct, so I think I would be ok with the balanced outputs on the DirectStream into the ZMA (also 2.8V).

I'm pretty sure the guys at PS Audio and forums are tired of hearing me say I wish there was more voltage for the input of my ZMA. They think I'm nuts.

A new review on the DS.

After living with the great gain from my PS Audio MK 2s I'm leery of the new voltage from the DS, will just have to see. The only real problem I would have (using single-ended input) would be from my DVR, I'll likely have to use the "Narrow" DSP option but that's okay. I'd rather not use the CSP2+ (surprised me to discover I didn't prefer the preamp in front of the Mk 2).

Should be sending one of my Mk 2s back for an upgrade in a few days.

Well, my DS is on its way back. I enjoyed my time with it. My AA front end keeps me involved in the music where I can't justify keeping the DS for just Redbook. The good news is, it free's up some serious cash for potentially the Auralic Vega an others including the Benchmark DAC2 HGC! It's all good, an the fun journey an enjoying the music with my CSP3/ZMA combination continues!

Interesting. Personally if you're not keeping the DS I wouldn't bother with the other two but then we're different. Smiley

Wow, I'm surprised - Stone. I got my MG-944 back late last night, and I put some Beatles, Hugh Laurie, and Wailin' Jenny's on random last night and was again blown away by how much detail I get with the DS.

Plus, I really missed my 944s. They really sing with the ZMA.

Wait, did you ever try the new firmware?!?!

Per that review: I have the Schit Bifrost (with the uber upgrade).   Yeah, I'd say there is a little difference with the DS...like about the size of Texas.

Given that Raven has once again spoiled me, I am going to hear a demo of the Chord CuteHD (or Ex).  It's supposed to do redbook well and is about 1/3 the price.  The fact that it does DS is a bonus.

If I hear something close to what I heard in the DS playing redbook, I will likely buy it.

I'm open to any other sub $2K suggestions if you guys have any.

There was a thread about DACs, including the Hugo a few months ago. I tried to ignore it because I was quite happy with the Oppo till I heard the DirectStream.

If you could find something that renders music somewhere between the Oppo and the DS, for under $2000 - that would be a real winner.

Pal,

My opinion: buy one of the used PWD Mk IIs out there (one on audiogon right now for 1600). I think mine sounds amazing (well, one of mine) and then in time you could upgrade to the DS I bet.
