Jolida - Fusion 3502 tube integrated amp ...
I took a chance for the fun of it, ordered the Jolida Fusion 3502. Could be a fun little piece.
Jolida Fusion 3502S Integrated Tube Amp
Combining the best of the JD302CRC and JD502CRC designs, Jolida dramatically elevates audio performance in the Fusion 3502S. With a flick of a switch, you can set this integrated to operate with 6550, KT88, KT120, KT150, or EL34 vacuum tubes. The EZ-bias circuit is completely redesigned to deliver a bandwidth of 8Hz—130kHz. Fusion 3502S also includes ESA clarity coupling caps, high-speed diodes, and DC voltage to the preamplifier tubes, improvements that lower the noise floor and increase frequency, linearity, air, and dimensionality. And let's not forget the sound. The moment you hear it, you'll know this integrated amp's clear, smooth, and three-dimensional signature is the kind only gleaned from tubes. All you need is to pick black or silver, and the tubes of your choice!

Excellent price and products. I had one of EL34 int amp before. It was very very good :)

Sorry that the Barn is picked clean of the good EL34 stuff. I did get Shawn a quad of Phillips rebranded Mullards XF1 and XF2s for only $100 and he was over the moon. Of course he wanted more (especially the metral base Phillips XF0), but only EH are left...
If any more reapperas, I will let you know.

Thanks Norman. It will take a quad of anything from 6550, KT88, KT120, KT150, to EL34.

re: Jolida - Fusion 3502 tube integrated amp ...
Joe-If you can run KT-150 tubes in this IA, please do. They are the bomb.
-
re: Jolida - Fusion 3502 tube integrated amp ...
I will. I'll run it and break it in with the stock EL-34 and switch to KT-150's probably late next week.
I know it's not an expensive amp but other Jolida gear have been getting great feedback. This one has a few upgraded parts so it should be fine.

I hope your Fed Ex delivery isn't like my Fed Ex delivery. Mine are famous for gaming the system and entering into the system that they attempted delivery and no one was home-even on packages that no signature is required like my last shipment of tubes. All because sometimes they just don't feel like making the drive to my house.

re: Jolida - Fusion 3502 tube integrated amp ...
Usually very few problems. Fingers crossed.

re: Jolida - Fusion 3502 tube integrated amp ...
Joe, did the amp arrive today? Nothing like the sound of EL-34's. No reason to change those out.
Sent from my mobile.

re: Jolida - Fusion 3502 tube integrated amp ...
Apparently the amp did arrive.
For EL34, he needs some great NOS Euro tubes. Phillips/Mullard? XF codes?
-
re: Jolida - Fusion 3502 tube integrated amp ...
Hi Doug,
I just set it up and biased the tubes. It's a bit constricted and a little bright, definitely needs break in. It absolutely shows promise. I think it will be great.

re: Jolida - Fusion 3502 tube integrated amp ...

So far so good.

re: Jolida - Fusion 3502 tube integrated amp ...
I'm with Doug and Norman, if the EL-34 will drive what you need it to stick with it. Of the tubes that amp will run it will be the most similar to the LM.

That's great Joe. A nice little Christmas present with its own bright lights!

It has plenty of power. I was itching for EL-34 again. I'll let it settle down before making final judgement. It a tad bright on top but is way better now with a little time on it.

re: Jolida - Fusion 3502 tube integrated amp ...
12AX7 driver tubes? Yes, some nice Phillips MW deltas our Tungsram or the US Groove tubes (Mullards clones) should do niceley.
There may be few PMW deltas left in the Barn, a quad or so. Should I go looking in the new year? Used, so no strength guarnatees, but cheap, so….
No 12AT7 (ECC81) left, AFAIK.

re: Jolida - Fusion 3502 tube integrated amp ...
Hi Joe,
Nice amp to play with!
RE: the 12ax7 drivers, you might try some NOS 5751's in that role too. They can be really nice in lieu of the 12ax7 depending.

I'd take a chance, sure.

Thanks Mike.
For under $1700 delivered, this amp is outstanding. She's opening up and smoothing out. Just incredible with tons of bass. Amazing.

re: Jolida - Fusion 3502 tube integrated amp ...
Thanks Allen. I can't believe what I am hearing. This amp, a modest pair of speakers and a decent source makes a wonderful system.

Absolutely Joe. Something like this or a similar LM amp and a pair of small Harbeths would make a great system. Of course some guys around here might use it as a nice little bathroom set up. :b

re: Jolida - Fusion 3502 tube integrated amp ...
Hi Joe,
Looks like a cool new addition to the stable. How does the built quality and sound compare to the Rogue audio gear you have had in the past? They seem to be in the same price range. Merry Christmas

re: Jolida - Fusion 3502 tube integrated amp ...
Hi John,
It has been a while since I had Rogue but I think the build of the Rogue might be better. From memory, this amp seems a little sweeter, probably because of the tubes. My volume knob drags a little on the faceplate and is okay for manual adjustments. I had to pull it out a few millimeters so it did not touch the faceplate to allow the remote control volume adjustment to work. That was not a big deal but otherwise, this amp is outstanding. I still want to get/hear the Rogue Stereo 100 and a Primaluna HP, but they are twice the price.

re: Jolida - Fusion 3502 tube integrated amp ...
Mark has the Rogue stereo 100 in stock and some other new toys I'm going to listen to next week. I'm seriously contemplating picking up a Primaluna Dialogue HP integrated or the Primaluna DiaLogue Premium Preamp before the price increase, I can't makeup my mine which way to go.

Do you already have an amp? If so, what?

I don't know anything about that amp except it retailed for $15k and it's SS. I don't obviously know if the amp is $15k good or if it's just overpriced. The cost to weight ratio isn't great, but that doesn't necessarily mean anything. If you like the amp, the Primaluna preamp doesn't seem to be a good fit. I know some people feel the opposite, but if you are going to mix and match tubes and SS, it makes more sense (to me) to match a SS preamp with a tube amp than vice versa. Many relatively inexpensive tube preamps tend to be noisier than SS preamps and that noise gets amplified by your SS power amp. Tube power amps tend to be quiet unless you have a bad one. Combine a SS preamp with a quiet tube power amp and now you have something.

True…I have seen some RCA ones locally.

re: Jolida - Fusion 3502 tube integrated amp ...
What's going up, when and how much?
I am sure the Rogue 100 is awesome. I like the idea of multiple tube use in the Primaluna gear.

Update:
This Jolida Fusion 3502 is simply outstanding. The first night it was a little harsh like some new gear sometimes sounds. Now it is opening up beautifully, surprising amount of bass with 3D and depth. Lots of air around voices and instruments. This integrated is a knock out home run. If you want an inexpensive tube amp that can play so much higher than its price would suggest, run and get one. Mine is going nowhere. Now I am even thinking about the new Jolida Luxor VTM 100 monoblock tube amps coming next year.

Very nice Joe. I'm glad you're enjoying this amp. Is this more crummy Chi-fi or is it made elsewhere?

Actually, the juxtaposition of your two statements was hilarious.
