100+ Head-Fier
Hmm, it`s interesting to read this. I am using JJ 6SN7 in my Lyr3 which I am using it as an preamp for my headphone rig. Overall my JJ sounds very nice and I think better after more than 100+ hours, than right after it arrived. Definitely cleaner, more spacious, better control and overal better sound performance like the original Russian NOS stock. Russian stock tube which came with my Lyr3 is not a bad at all. It is warmer, with less detail, less soundstage and definitely less layered bass. JJ is just better in every way. But, sometimes the Russian is also fun. It depends from the mood and I am happy, that I have that option to choose the sound taste according my actual mood. Now I am waiting for some more tubes (Tung Sol, Electro Harmonix, PsVane).
Why I am writing this, I really am curious, how does the other tubes will sound, because overall I like my JJ 6SN7 so much and also Schiit include them to ship with the Lyr3 and probably with Freya+ as well. If these tubes will be bad, I think, they will definitely not include them into their options.
And the best part about this is, they sounds good, actually very good based on my experience. And these are new production for very friendly price. It means, they are not hard to get, they`re not expensive and you have a much better chance to get good paired tubes, like with some NOS options out there, which are getting more expensive and harder to pair.
I was very disappointed when I saw that my new Freya+ came delivered with JJ tubes. Of course all of this SQ stuff is system dependent. However, a ride around the net, and even around this thread, reveals that the JJs have a reputation for a harsh upper end, and that certainly is my impression. Schiit continues to market the Freya+ showing Tung Sol tubes and promoting reviews that give specific credit to the Tung Sols for the fine sound of the Freya+ in tube mode. Permit this cynic to note that the JJs are cheaper to send along with the preamp than are the Tung Sols. As we teach in corporate finance, cost cutting goes directly to the bottom line. From my point of view, the price of the Freya+ has gone up by the cost of 4 Tung Sols. But I can see where my SQ is going and the purchase is still worthwhile to me.
