Paul and Ted told me they used those inexpensive output transformers intentionally. They wanted them to be a little lossy or something. So that was an intentional design choice, not a corner that was cut.

The only way I would even consider different output transformers is if I could find the same ones, but with a higher output voltage. The Output voltage on the DS isn't as much as the Oppo, and that's my one disappointment with the DS; it just doesn't drive the input of the ZMA as well as the Oppo or my Otari.

Ted's prototype used Jensen transformers that cost 10X more than the
DS transformers.

It will be interesting to see JA measurements of the DS Art Dudley is reviewing.

Does your ZMA have balanced inputs?

Yeah, I brought my ZMA in to Steve and had him add the XLR inputs. I really like them with my Oppo and Otari Reel to Reel - it definitely adds something to the ZMA. But that extra something isn't coming over with the DirectStream DAC - I thought it was voltage, but Ted said the voltage only equates to 3db and has "nothing to do with slam".

LR,

Appreciate your feedback on the DS.

I was concerned about its ability to drive amps directly.

Glad I waited, I don't want to add a preamp.

Wonder when someone will start offering an upgrade for the cheap output
transformers used in the DS.


This is what I got from Paul on the subject.


Quote:
PAUL - For two reasons: cost and the need for a 'bad' transformer. The Jensens are hideously expensive and would have raised the price of DirectStream significantly. But had that made a lot of performance difference we wouldn't have hesitated.
A stock high end Jensen isn't the best choice for DirectStream's output stage. What Ted wanted was a 'bad' transformer, meaning a device that has relatively high leakage current and rolls off on the top end above a certain frequency. DS output transformer is custom designed to be our low pass filter, giving you flat frequency response in the audio band, but above the cutoff, start rolling off the noise. To do this you don't want a 'perfect' transformer that extends out too far and has low leakage. You want the opposite. So what we use is custom designed for us, then Ted writes code to match perfectly the response of the transformer.
Perhaps someday, if we wanted to do a 'whack DAC', we would look to Jensen to wind us a custom transformer and see if it was better, worse or indifferent. But bottom line, we don't want a 'perfect' transformer for DS output – because the perfect transformer is one that doesn't measure so good in normal circumstances.


So this gist is that it's part of the circuit and changing it, changes the filter design that Ted work so hard on.

Yeah, for sure, enjoy the weekend!

If all goes well, and I ever make it out of Peoria, I hope to be listening to some HR-1 on my DS via ZMA (I love our secret code language)

LR,

Sorry, but I don't buy Paul's transformer story.

As you said, "that extra something isn't coming over with the DirectStream DAC."

Like I said, it will be interesting to see JA's measurements of the DS Art Dudley is reviewing.

LR, did you get the HR-1's?

I have been on a Speaker quest too. I bought the Sonus Faber Venere 2.5 today! Absolutely an incredible Speaker. I can't get them hooked up to my DS an ZMA until Monday night.  Anticipation..... .  They punch well above their weight class.

Those are beautiful speakers (SF always makes sexy stuff)! ... But what happened to the Gallos?

Gallo's are good...but the Faber's are better.

Some things have to go! I've decided if I'm not using it consistently, I'm Selling it.

I will list in the Classifieds...soon, what I'm selling. At the lowest end of cumulative/lowballed...I have $3500.00 of stuff that needs to go. A good problem to have.

I exhausted everything from 8k down.  The 2.5 Venere's are literally a loss leader....for Sonus Faber.

What, these old things?





I'll post more on them later. I have Palomino coming over for a review today, and I don't want to skew the results in case he's checking the forums before he comes over.

Having a friend listen and review without prompting helps me validate what I'm hearing. For example, if I play a certain song and the cymbals at one part sound simply amazing, I'll play that song for my listening partners, and if they say "wow those cymbals at that one part were amazing", then I know I'm on the right track and not tricking myself into believing there is an improvement when there isn't.

Palomino has been great for this as he's as brutally honest as I am. Helps "keep me honest" as I say it. So when you hear both of us post something positive or negative, that's probably already been through our "peer review" LOL

I hear you on the validation. My girlfriend has validated the DS an my Sonus Faber 2.5 Venere's. She can hear.  

Beautiful HR-1's!  Enjoy, I have some family cool stuff to do today and busy until tomorrow night. So, I can't get to my Speakers till then  :'(.

Enjoy!
