    Thanks for the tip Misterroggers. BTW what tubes do you have set up in prep for your Studio arrival?

    anyone ever use this site? I called him up and he said he got a big batch of 1950s tubes that were selling very well, all double plate, he lists the pairs and how closely matched they are right on his site.

    I regret selling my quad matched monoplates. I am going to delve into the closet to see what I have left. I think I might have a pair of grey plates somewhere.

    Just an observation if you have old stock tubes like RCAs, Hytrons, Sylvanias, etc. that haven't been used in a while; they take a while to have bass. Initially they may seem lean or even strident and reserved. A week or two of normal use should do the trick.

    The Studio-Ts are all sold out, pending that we can get more of the unobtainium interstages from Tribute. A few Studio-Ms will be available. I've just ordered five pairs of the Monolith interstages, so we should have six pairs total. One of the Studio-Ms will be my personal amp.

    Since I am quoted here I think I should chip in.

    I actually like the Teton and 445 equally, but the 445 is too lean for certain types of music on the HD800. The Teton is more euphonic and 445 more clinical.

    I agree with ZD on the technicalities. Staging is better on the 445. The stage feels endless on the 445 whereas on the Teton it is more compressed. I tried playing Nuc dimittis by Stile Antico and only the 445 (and not even the T2) gives me the feeling that I am in an expansive heaven. I am told the slightly compressed stage of the Teton is how Romaz managed to differentiate the Teton from the other amps at Big Sound. The 445 also has sweeter/more extended highs than the Teton and has better transient attack from the upper mids onwards (but the Teton, when coupled with the HD800, has more bass quantity and slam).

    On balance, however impressive the 445 may be especially with classical music, I feel that the Teton moves me with the music a bit more. Technicalities are not everything.

    I assume mine are Studio-Ts? Or not?

    Hello as I see it you have 5 studio Ts built and you have 5 studio Ms ready, I am no 12 on the list. Where does that leave me? I think I would be happy with either.

    We'll figure this out. I want to give people already on the T list to switch to M in order just to be fair since they could be waiting forever. We're still trying to get an ETA from Tribute. They tend to be quiet, and then all of a sudden ship 10 to us.

    Hey all - apologies for going dark; life, work, etc. Studio landed as expected, and a quickly found out that both balanced and SE outputs of my Yggdrasil are too 'hot' - causing distortion with recordings that are recorded a bit 'hot' too. Lower output recordings played fine. I've swapped in a couple of other DAC's (output <= 4V RMS), and everything is as expected - meaning, no distortion, and sounding great. Right now, I'm assuming this issue is unique to my Yggdrasil. I'll take some measurements this weekend to see how hot my Yggdrasil actually is. It's a production build, but definitely from the first batch. I've used it with a good dozen amps, and Studio's the only one that's had an issue with output levels. I don't mean that as a knock in any sense, just as a data point.

    So. Haven't had any real time for listening, and the listening I've done has not been with my best DAC (Yggdrasil). I'll have time this weekend for real listening, impressions, and photos. Photos will not include pictures of the crate, because there isn't one :) For reasons I'll let Marv address, EC opted for a more traditional box with foam. I will say though, that everything was packed very very well.

    Adam, have you tested with Yggdrasil yet?

    Would be useful to confirm with a second source.

    We've tested with Yggdrasil, Gungnir MB, and Gungir DS (all 4Vrms). We actually had the exact same issue with a pre-production Gungnir MB, but no problems with a production unit. The Cinemag transformers are rated for 18dBU which is 6.14Vrms. A little bit over that, and the transformer could start crapping out very quickly. We are trying to replicate this issue (same DAC, same recording, same pot) as it would be better if we caught anything earlier rather than later.

    I have an early production Yggdrasil and I haven't hit this yet. Any tracks I should try to see if it's an issue?

    We had the Studio turned up all the way to max volume to power your speakers and didn't hear anything odd. Mike mentioned the distortion (I assume the garbly crackly kind) came in on certain recordings with the volume up to 10 or 11 dots. If there is a little bit of DC, that could do it. If it comes down to it, I'll ship my Yggdrasil to Mike to get to the bottom of it.

    Yeah, It seems to be a too powerful Yggdrasil. I haven't had issues with my Yggdrasil/Studio combination yet. It does get some use with my TV + speakers.

    Yup, though Jason's dubious that it's high. I get it; the design and BOM would explain some variance, but not much. We'll get it figured out I'm sure - just need some time to measure, etc. I'm going to upload some of the music that's distorting, make it available to Marv and you too Dr - if you want.
