Still a bit out of my league but thanks for the suggestion. 

Any opinions on the Moon products?  I've always liked the sound of their stuff overall.

this looks interesting, if a bit unconventional.  but. i'd want a 30 day trial listen...

note the reviewer said it gave up nothing to his two 3-times more expensive phono stages he normally uses.
and, i might want to wait a while, based on the email exchange i had w/mr parks - upgrade will be in the works soon:

q (moi):
hi!

interesting product!

a couple of questions:
- when are you going to include the spdif function as a factory option - at the same 96khz speed as the internal dac? (easy enough mod, but who wants 48khz when 96khz is there?)
- when are you going to go to 192khz (or higher; and also for the spdif out?)?
- when are you going to have a socket for the op-amp(s?) to allow for easy op-amp rolling?

thanks!

(tho it appears that if you don't wanna do the easy spdif out mod, you can now get it already done for $100)

a (mr parks):
Thanks for the email, Doug. Happy to answer your questions:

- Hope to switch the 48kHz to 96kHz this fall. This will require a factory mod for in-service units, though the DIY mod at 48kHz will remain an option for those, too.
- No plans for leaving 96/24 at this time. Part of this is leaving the hardware alone as much as possible to focus on software development. Have some firmware upgrades coming this August (free for all Puffin owners) that will add some revolutionary functionality. The other part is that 96/24 is a sweet spot engineering-wise: solves the Nyquist and aliasing issues that 44.1kHz and 48kHz had, but permits much better (and efficient) DSP of the audio frequency band. This latter engineering bonus just isn't a part of the equation for those using digital as a transport mechanism only.
- No plans for a DIP socket.

Warm Regards,

more info from mr parks (after i told him 'd posted my query and his answer):
Appreciate the interest, Doug. Word of mouth is definitely my main method of advertising.

The SPDIF upgrade will probably be around $100 to $150 plus return shipping. I'll do a discount for anyone who purchased a 48kHz SPDIF modded Puffin from me, too. There will most likely also be a price increase at the same time, so no reason for folks to hold off.

I'd try to buy a Salas phonostage. They come up for sale once in awhile.

I'm not saying to build it yourself.

You'd need a vastly bigger budget to find something like most of the builds.

i understand - find one someone else's, already built.

from looking at the boards, i agree; it would take a sizable investment to buy something commercially available that would out-do this. (or an amazing over-achiever.)

Nice, already took a look!

It's feedbackless in a better way than PS Audio's new flagship phono. You can roll some nice caps, and most people use some good ones. It's got a bit of a following.

Interesting piece - but...  Not sure why I would be going to analog only to have my phono pre convert to digital then back to analog???

according to those who use it, your records still sound analogue, fwiw....

If your looking for a mm phono stage check out the Decware ZP3. All tube, all point to point wiring. I had one for years. Loved it. $1300 new. Lifetime warranty. Decware is rarely mentioned but they know what they are doing. The real deal.

steve deckert left a bad taste in my mouth quite a few years back, when he blatantly lied to me about how one of his low powered amps would do driving my hi-efficiency - but 14 ohm - speakers.  he said it would be great.  it totally sucked - full gain on my preamp wouldn't drive the 97db-efficient speakers to decent volume levels.  and i had two other 4wpc amps that would drive you out of the room if you got anywhere near full gain.

i'd rather not patronize  decware.  if you find something used, at 25% of retail, then maybe it'd be worth a try...

ymmv,

Bummer. I've had similar experiences. But the guy didn't lie to me. He was just wrong.

well...  in my case, i probably should have known better.  but his explanation sounded plausible.

his 4w amp was rated at 4 ohms.  i doubted it could drive my 14 ohm speakers very well, even tho rated 97db/1w.  (and my speakers were actively crossed over to subs at 80hz, making it an even easier load for an amp.)  he assured me that, tho his amp was rated at 4 ohms, that was to let folks know it could drive more difficult loads, and that it would be fine driving an easier load.

was he just wrong, or was he lying?  and, if he was wrong, what does that say about his engineering skills?  you be the judge.
