RR, I think you are spot on that this is one way to interpret the Grant Fidelity assessment of the Shuguang tubes. Like buying old Jags; cars were wonderful to drive, so long as you could drive them.  Reminds me of an old cartoon that showed a dealer, and a buyer discussing price, and the dealer says something like: "And here is our Platinum Premiere Package; it includes a stand-by mechanic."

Well, I was out sick a couple of days, so didn't have a chance to set up my Torii for its burn-in cycle. But it is going now. 5 hours on and off.  I have an iPod set up to shuffle-repeat through its entire library, with the Torii set on a heavy duty timer cycled every 5 hours. That way, it should only take the V-caps about two months to settle in. Wink Actually, it should take less than that, because I will do the cycling thing only for about a week, before I bring it home. The Radials are due here Tuesday, and Sarah just told me the Ultra is shipping out today.

Such a lovely piece of equipment. I am thinking of changing my handle to Valve Drunk. That way, you guys can call me VD in messages.

PR, what is the verdict on the Treasures? Or I should search for it in another thread first? I'll post this first...... .

Also, big price difference between goodcomponents.com and grantfidelity? I suppose the Grade A at grant vs. what goodcomp. carries? I don't know? The fancy box pretty, or paper box scares me too from goodcomponent. I don't have a tube tester.... . Steve does, so I will buy them from him.....if you guys that use them think they are worth it too......like the reviewers.

SOT, I absolutely love the SGT 6CA7-Z tubes. I have listened to the stock JJ EL-34 and I have the JJ 6CA7 as well. I have some NOS Mullards and Svetlanas also, but I haven't listened to them. I am no fan of Chinese tubes, nor do I believe that simply because they are Chinese, they cannot be good. I ordered two matched quads from Grant, highest rating. I ordered a third quad from a fleabay seller at half the price as the Grants, for backup, but have not listened to them; they are slightly different in appearance only on the bases; the third quad was not shipped in the luxury box, but it arrived safely. The Grants tested as billed on my B&K, and so did the third quad. Bearing in mind that my Toriis (with V-caps) are still breaking in, so there is every reason to believe that their sound is still evolving, here is a summary of what I hear (I am not a big long review writer):

1. Sublime liquidity, a smoothness that is clear and deep.
2. Layers of complexity, which in combination with the depth and detail, amazing detail, produces a deep, wide, tall soundstage.
3. Soft highs, but not lacking air or detail around instruments and voices.
4. Well-controlled taught bass.
5. Very quick transients, with what seems like natural decay.

Now, maybe a year from now, any tube will sound like this in this amazing amp. Could be, but the JJs do not sound this thorough, this complete, not yet anyway. For now, I am delighted.

Thanks PR, after I have spent some time with my Torii and the JJ's shipped with/break in of Amp as well......... .  I will have to order Quad's of the highest rating. The curiousity over the next 6 months to a year will itch at me in a good way. I can rationalize the Treasures, because I bought the Torii before the price increase. Thanks again, Stone of Tone.

PS-where do I find that list of where my Torii is in the Que (I could call)? I remember seeing one for Speakers one time.......... . I'll check the Blog or Whats New Tabs.

I see you posted the amplifier waiting list... it seems no mater how fast we try to build them the list continues to grow.  That's ok, I've learned a couple things in the past 15 years and the first is that you don't rush a good thing.  We can build and ship between 2 and 4 a week if that's all we build.  There are another 50 amps of different models that you don't see.   With the small addition to the shop and another 6 months of training we can get another full time guy or two and get product back down to 3 to 4 weeks.  It's been around 8.5 weeks all summer and shows no signs of changing anytime soon.


On another note, someone with the Treasures tipped me off about JJ's new 6CA7 and it's a winner.  I am now shipping all Zen TORII's with this 6CA7 in place the of EL34's.  Very nice indeed.

-Steve

Steve, Can you explain what you hear from the Shuguangs compared to the JJ 6CA7?

I understand Steve. Your right and you don't rush a good thing. When it arrives it arrives. I told myself I'm not calling Sarah, she has better things to do. Yes, the new 6CA7's........I look forward to hearing them.

Cheers, Stone of Tone.........and nice new addition to the shop! You are busy.

Absolutely. In this line of work, right is preferable to fast.
