Alright so I haven't had a whole lot of time to experience my Lyr 3, but I do have some small impressions to share for those who may be interested in getting one down the road.
Listening was down using Tidal -> Gumby -> Lyr 3 -> LCD2c
I purchased the version that was straight amp, no additional card added. However I'm beginning to wonder if I should have went with the multibit version. I swore I would never sell my Gumby after getting it, but I don't really need the balanced outputs or dual rca outputs. It seems crazy that a full multibit card can fit in the alloted space in the Lyr 3 chassis. It would make a great little combo that would free up some much needed space on my shelf.
Speaking of the chassis, I have to say the new design is pretty great. I was afraid coming from the old "U" style chassis it wouldn't look nearly as nice sitting atop my Gumby, but it looks fantastic. Schiit really knows how to make a striking product that looks sexy, but still remains understated and not overly gaudy.
Getting to the sound portion, I can't say I'm hugely impressed with the 6sn7 tube style. Schiit is right they are a very linear tube, almost to the point where I feel like some of the tubey goodness is missing from what I found when I first discovered the original Lyr. I'm not saying that they sound bad, but of all the 6SN7s I've tried so far I haven't found one that gives the same extension, body and impact of a good 6922 or 2c51. I got a Tung-sol 6sn7gtb for a reasonable price and it was by far the best sounding I've found so far. However after switching over to a 6DJ8 Bugle Boy it sounded a little flat, almost anemic. Kick drums and bass lines had their punch back! Also the sound stage seems a little more compressed on the top and bottom. It does extend fursther out to the sides, but doesn't reach as high or low. Also it's not quite as 3D sounding, but that could be because I'm used to a more intimate sound stage with the LCD2c. I have a few other 6SN7s coming in later that I will try, I hope they give some more excitement than the ones I've already tried.
I don't want people to think that the 6SN7 is a bad sounding tube, I just don't think I've found one yet that gives me the same tube "feels" that I get from some of the 6922/2c51 variants. I think folks will be happy with what they hear on first listen and if they decide to chase some of the other tubes out there they are going to be thoroughly impressed!
