All I can say is after one evening of listening is WOW! It's been a while since I had tube finals and never on power-hungry Maggies before. This Jolida JD-1000RC really sings! I'm going to listen to the stock tubes a few months before rolling in some Mullard EL34s and 12AT7 drivers.

Try the Belles Reference 28A Preamp (and its excellent phono section). I will not try to explain what it did for my system in audiophile lingo, but suffice it to say that it is not going anywhere anytime soon, maybe never. I know you may have said that about your Nad. But, I thought I had an excellent preamp in the TAD-150 until the Belles blew it away; and it wasn't even a contest. I am using mine with a Cayin TA30 tube amp and the results are stunning. The phono section is dead silent.
Maybe I'm seeing wrong but it looks like an enclosed cabinet with not much room above or to the side.
Life has lots of trials and lots of music to help us through them.
plus I leave the front glass door cracked open when listening.

Holy Crap Henry!?!?!How is the output tube's biasing scheme on that thing? Does it allow for individual output tube biasing? Two matched quads of even late, XF4 series Mullard EL34's will run you into kilo-bucks in the NOS output tube market!
What does it come with for EL34's? I kind of like some new Russian EL34's in my Dyna MkIV's.

EL34 version of the 12AX7-Ms. I've got a pair of matched quads. They set me back just over $100 per matched quad. There are two ways to bias on the JD-1000RC. You can just use the bias LED next to each output tube. There is a trim pot just below each LED. Or you can use an external VOM to the 4 test points per channel.
The stock tubes are Jolida branded, most likely sourced from the same Chinese source as other Jolida tubes.

I think these are about 40 per tube if I remember right....Check also to see if you can roll C6A7 tubes or KT-77's. I find the KT-77 tubes have much more air and high frequency response and a very tight bass line.
My preference is the Phillips style big bottle C6A7's that I have in my Precision Fidelity amp. I am getting superb bass and midbass and a very clear midrange. I like the highs too, they seem natural and not tizzy in the least.
although in my case (Rogue Atlas), they are E-H, not nos.
I also have used the JJ KT-77 in the Atlas and it too is excellent.
You cannot go wrong with either.
These sound like the same ones. EH builds these Phillips equivalents and they sound really full and rich.
Electro-Harmonix 6CA7EH
matched quads of JJ KT77s. They likely will be the first set of finals I roll in.

Can you get 100 db out of them?
With push-pull parallel EL-34s that thing should come pretty close to achieving it's 100 watt a channel rating.It looks like an integrated preamp version of the VTL Compact 100 to me.
I wonder what that sucker weighs?

Woops. It looked like a pair of EL34 per side. Sorry. 100 watts should drive those pretty well.

That said, if it is anything like my Jolida JD-501 the 12AX7's and 12AT7's have more influence on the sound.That, and a coupling cap upgrade (Jensen's) make all the difference.
I do use NOS Amperex Holland made EL-34's, but I purchased them years ago before things go crazy.
I still have some NOS EL34s. I sold off and traded away probalby 8 matched quads over the years. All before they passed the price of gold, of course.I kept some of the best but man-O-man, if I had a dozen old Mullards back in my hands again to sell now...
I am very glad I kept my El37s, KT66's and miniature signal tube collections intact. No way could I replace them in today's market.
Sure wish I had that sealed, factory matched, Gold Lion KT88 octet back tho.
