Can't believe nobody has mentioned the ZMF Atticus yet, so I will.... :)

Pretty interesting, how you've got that Loki equalized. Guess you rilly like a lotta BASS! :)

Rolled in that 6CG7 (actually an RCA). I was actually mildly startled at the difference from the JJ 6922. Everything sounded much more relaxed, and pulled apart...by which I mean the soundstage was much wider. The players don't sound like they're sitting in each others lap now, though I wasn't...

Don't think you'll get any more power much less than 50 ohms. But if the amp isn't overheating or blowing up, I guess you're good. :) The output devices are SS.

Howsa bout the no label JJ 6922s? I got three of em right before the Russian embargo hit, about $22.00 ea from Tube Depot. They're smoother sounding than the GE 5670's I was using by quite a bit. Like 'em a LOT! That said, just ordered a NOS Sylvania 6CG7, the closest thing to a 6SN7, only you...

Apparently we're a weird cult of HD580 obsessives. Yup...if it ain't broke, why fix it? :)

Smallpie is a scholar and gentleman. Atticus exactly as described, shipped within the time frame agreed upon. What's not to like? Thanks!!

Well, never mind...I see their website does have now the 650 cables, but the earcup grilles are nowhere to be found.....

So now that Sennheiser has been SOLD to some damn hearing aid company, who seems to have no interest in supplying parts via the internet, does anyone know where I can get some good old stock HD 650 cables and earcup grilles for my aging 580's? :)

PM sent....

Not meaning to pick on them, but it does seem like every time I do a search on a Focal model, this issues seems to come up a lot in the threads. Have they fixed their quality control issues? If not, I'm gonna move on....

OK, Adydula...you were right! I took that little Vali 2 to my downstairs system, compared it head to head with the little all tubed EarMax OTL amp that I have been using for 25 years. While the Vali 2 was not quite as tubey as the EarMax, with the GE 5670/adapter it is close enough that I have...

OK...so whaddaya recommend as the best bang for the buck tube for this amp, with HD 650's?

Just got a new Vali 2 'bout a month ago. My 1st listening impression with the stock tube was "Gad...they weren't kidding when they said it had a lot more distortion than their Magni 3 +!" A lot like my Asgard 2 as to overall warmth, but with a layer of crud over it. Adding the GE 5670 tube...

Your issues with closed back cans I agree with. Sennheiser HD 580, or HD650 I can wear all day in total comfort. That's why I stick with them. The Drop HD 5XX is also quite good.
