postjack Posted January 3, 2008 Report Share Posted January 3, 2008 I posted about this over in the TTVJ forum, but I'd like to snag the HC opinion as well: http://www.ttvj.com/index.php?main_page=product_info&cPath=5&products_id=1110 This phono looks very versatile. I like the idea of a tube MM stage, while throwing in the SS to beef up the output for MC. And Todd says it should be available in 2-3 weeks.

It certainly looks interesting to me. I just need a turntable. Quote Link to comment Share on other sites More sharing options...
luvdunhill Posted January 3, 2008 Report Share Posted January 3, 2008 well, there are people out there that can implement switching supplies for audio, namely Ed Meitner... whether or not the benefit outweighs the potential problems, sir is the question!

n_maher Posted January 3, 2008 Report Share Posted January 3, 2008 Jack, In either case (MM/MC) there is a SS gain stage prior to the tube gain stage. For moving-magnet cartridges, the preamp uses a high-quality audio opamp gain stage at the input. The use of a opamp here provides very low noise, and a low impedance to drive a passive RIAA network. <snip> For moving-coil cartridges, an additional solid-state differential amplifier stage is inserted before the opamp stage.

Ah, so it is hybrid all the way. An additional SS gain stage. My apologies for the error. Quote Link to comment Share on other sites More sharing options...

No worries, I trust Pete to have done it right so I wouldn't worry. People judge his work with a bit too much focus on the low-voltage hybrid which is kind of like deciding whether or not you like a car based on the brake pedal cover.

postjack Posted January 3, 2008 Author Report Share Posted January 3, 2008 Of course, the most important question remains unanswered: how does the phono stage look? Todd said he'd put up some pictures in the next few days. Quote Link to comment Share on other sites More sharing options...
Grand Enigma Posted January 3, 2008 Report Share Posted January 3, 2008 pretty poor SNR. Quote Link to comment Share on other sites More sharing options...
n_maher Posted January 3, 2008 Report Share Posted January 3, 2008 pretty poor SNR. I was under the impression that most phono stages had pretty poor SNR due to the extremely high gain required, have I been misled? Most solid state ones that I've seen aren't above 80 and my bugle isn't rated much better than the TTVJMH. Quote Link to comment Share on other sites More sharing options...
luvdunhill Posted January 3, 2008 Report Share Posted January 3, 2008 pretty poor SNR. I measured my Xono-ish clone on some fancy HP thingy they have here at work and it was around -83dB @ 1mV for MC and in the -90's for MM measured at 10mV. My cartridge is 0.24mV output... I used to have the numbers for the Klyne System 7 phono preamp and they were insanely low... even lower than say the Zyx Artisan which is ~95dB for MM Quote Link to comment Share on other sites More sharing options...

Dusty Chalk Posted January 4, 2008 Report Share Posted January 4, 2008 I was under the impression that most phono stages had pretty poor SNR due to the extremely high gain required, have I been misled? Most solid state ones that I've seen aren't above 80 and my bugle isn't rated much better than the TTVJMH.MC ones are especially difficult because of the additional gain needed, but not all of them. Specifically, whichever ones Hirsch and Juan use are both pretty good (and since Hirsch has multiples, I'll specify that I particularly like the one he has on his VPI -- I don't know which one it is, and I don't know which one Juan uses; I think I've also heard that little penguin logo'ed one, whatever it's called -- I think it's the Firestone Audio Korora). My X-LP2 is 75/82 "A" weighted (whatever that means). Quote Link to comment Share on other sites More sharing options...
soloz2 Posted January 5, 2008 Report Share Posted January 5, 2008 hmm... looks interesting. I didn't even realize this was coming out. Oh well... I'm waiting on my new phono from Mcalister Audio. Quote Link to comment Share on other sites More sharing options...

soloz2 Posted January 5, 2008 Report Share Posted January 5, 2008 oh, I know it'll take a while... I actually planned on it and ordered before I really needed it and planned on saving up for it while I waited. It's really only a week late at this point. I'm not too worried though. I'm sure that even if it takes a little while Peter will take care of me. Quote Link to comment Share on other sites More sharing options...

tyrion Posted January 6, 2008 Report Share Posted January 6, 2008 Wasn't the price at $695 or was that just a preorder price which I missed out on? Quote Link to comment Share on other sites More sharing options...
n_maher Posted January 6, 2008 Report Share Posted January 6, 2008 I guess the pre-order only lasted a day or so. You are right, Mike, it was $695 when Jack posted about it on Head-Fi but it's now listed at $850. Quote Link to comment Share on other sites More sharing options...

You are right, Mike, it was $695 when Jack posted about it on Head-Fi but it's now listed at $850. yup, that was probably my fault. I think me posting about it jogged Todd to get the price changed. $850 is getting on up into the "well I could spend $150 more to get a <insert $1000 phono stage here>" territory, so I'm going to wait for some more news on this player.

deepak Posted January 6, 2008 Report Share Posted January 6, 2008 Dude didn't you just buy a Grado phono-stage? Gear-itis in full swing in 2008 as well Quote Link to comment Share on other sites More sharing options...
tyrion Posted January 6, 2008 Report Share Posted January 6, 2008 I should have jumped at the $695 price but I didn't know much about it. I have mixed feelings on changing the price like that but Todd's a cool guy so I'll cut him some slack. It's $150 more. If it can compete with $1000 phono statges then at $850 it's a good deal. A lot of you guys speak highly of Peter Millet (I'm pretty sure I've never heard one of his amps) so I'm hoping this is a contender and add to that a chance to support Todd it could be worthwhile to give it a try.

guzziguy Posted January 6, 2008 Report Share Posted January 6, 2008 Maybe Todd would give you a loaner to take to MOA? If it's a good deal, he would be smart to do so. Quote Link to comment Share on other sites More sharing options...

Dude, you owned a Wheatfield HA-2, you've heard a Millett amp. Wheatfield = Millett. Quote Link to comment Share on other sites More sharing options...
