Instead of the five they used, I chose ten separate audio criteria. They had used a point system for each attribute, so I decided to follow their lead. Synergistic Research Tricon Tesla USB cable:Īs I thought about the best way to do this kind of tube review – with so many tubes – I had run into a 6DJ8/6922 tube shootout that was done some time ago.

So this review should be read with this in mind. Last note on my system – it is far from typical. A perfect microscope to exam the different 6922 type tubes. The thing about the Lyr – it's very sensitive to tube changes. And with these the Lyr was exceeding (to my ears and system) the Woo. So I started tube rolling, and after a year and over 50 different tubes, I found some that hit the mark. The Woo was extremely smooth with a fantastic mid-range – the Lyr with stock tubes was more dynamic and exciting – but rough around the edges. My last amp before the Lyr was the Woo WA6 - SE that I'd owned for over a year and had tweeked and tube rolled to perfection (Mullard '50s 5U4G Black Base, 6EM7/Woo Adapters). After owning a half dozen really nice headphone amps, both tube and solid state, I read the 6moons review of the Lyr, and decided to give it a try. Quick story on how I came to use the Schiit Lyr. I have been upgrading my system for a couple of decades with each component rolled many times – and I feel it has never sounded better. PS Note these are just one audiophile's impressions on his unique systems and with his personal preferences. And so on to the review and my conclusions. So I decided to assemble these awesome tubes together and give them an intense one week roll-a-thon. Especially after reading other tube shootouts (see the HK Audio Club 6DJ8 tube shootout link below). I had never compared directly the Siemens CCa's against this Russian glass, but just remembered how they had sounded. I'd had a long experience with the top Siemens, Amperex, Philips,etc.so the sound quality of these tubes came as shock to me.Īs much as I found these tubes to be really special – I always had a nagging feeling that the best of the very best of the 6922's out there – like the legendary Siemens early 60's Cca's or the Amperex 6922 '60's Pinched Waists, even the amazing Telefunken E188CC's would be better. After spending a year sorting and categorizing the different years and constructions, I found some I thought were the best 6922 type I had ever heard.

So I have lots of places to try these tubes and have found they make a major difference in each application.Ī few years ago, after researching different 6922 type tubes, I stumbled on to what I thought were some pretty amazing sounding Russian tubes. Most recently I have been active on the Lyr tube rolling threads, but also use this tube in my modded DAC, and in two integrated amps that drive different speaker systems. I have always been amazed at the sound quality improvements that some of the better of these tubes made. The idea of the Grand Tube Review came from my long (20yr+) tube rolling history with the 6DJ8/6922/6N23P/E88CC tube type.
