Give it a shot if you’re willing to gamble. I had a Conrad Johnson cav45 v2. Bought it from a guy that sent it back to CJ and did the SE upgrade which from what I understand is just rip out cheaper caps and add Teflon caps. He said it was a large improvement over stock caps. I loved that amp.
Long ago had an Exemplar Audio modded tube Denon 2900 that was one of the best cd player I had ever heard so good I bought his newer Oppo version. I also had a chance to hear a stock Denon 2900, stock sounded bad next to the modded player.
I was in your place once I had a Bruce Moore preamp sitting up not being used took out signal caps added some Jupiter’s and better resistors. Really made that amp shine for what it was. You just need to figure out what sound you want from V Caps to Jupiter and everything in between. Then there is new wire better resistors, RCA jacks it never stops. I think you can make that amp sound better if you don’t buy mismatched parts, beware.
