Jolida Fusion 3502S vs. Jolida Fusion 801

Thank you for the replies. I purchased the Jolida/Black Ice 3502s  with the Rike paper oil capacitor and Naked Vishay resistor upgrades a couple of weeks ago from Underwood Wally and I am very happy with the sound. This unit is very musical and well built with an excellent all metal remote and I don't feel that Jolida/Black Ice gets near the recognition they deserve and are a great bargain at their asking price. I am using the stock EL34's which sound very good and I would like to try KT150's in the future. BTW Underwood Wally (Walter)  is one of the good guys in audio and would not hesitate to deal with him again.

I've said for years that Jolida's only issues are that they're too inexpensive for many who feel "Mo bucks=mo bettah.", and remain, for the most part, un-reviewed by the audio press. And that's a shame as they're great sounding and extremely well designed things.

I have had a 502BRC for several years. Terrific amp at a great price. I agree that their products are very underrated.

I talked to new CEO "Jolida Jarred" a few times when I was purchasing my Jolida 502P (he's the guy who recommended the upgrade for about 100 bucks), and am surprised they're changing the name to Black Ice (Maybe only some of the Jolida stuff...not sure) as that's a road hazard to be avoided when driving in wintery areas. I suppose it's better than "Pot Hole Audio", or "Unfortunate Moose Encounter Audio"...but interesting products anyway.

Don’t know if this thread is still active, but anyway an update of my previous post is necessary... just to share my experiences with  some tube combos that sound great in the Jolida 3502c.  As with any tube amp, this one “likes” some tubes more than others, and the “sinergy” between the input and the driver tubes is absolutely critical for sound quality.  

As I said, I found that the vintage 5751s black plates triple mica, either GE, Sylvania or RCA sound splendid in this amp, even  above my fancy Mullards or Amperex 12AX7.  I tought that the 12AT7s were not as important, but I was wrong.  The vintage  Brimars 13d9 (a special quality 12AT7) can be had for about $ 20 each,  and are vastly superior to anything I tried...I mean, combined with the 5751s your Jolida will sound magical.  All this with the standard and quite good EH EL34s.

Currently running  new KT150s for a few hours, great tubes of course, but I feel they need a good burn in to reach their full potential.  No opinion yet.   However, the Genalex Gold Lion KT77s, driven by the above mentioned combo sounded so damm good that the bar is really high...
