Help Me Decide on my First Stereo Amp/Receiver

[Disionity]

Hello, I'm currently building my first stereo system and settled on a pair of Wharfedale Diamond 10.1 speakers, but still need help on deciding which way I want to go with an amp/receiver. Currently I own a vintage JVC R-S33 receiver that I recently inherited from my grandfather. It seems to function well enough, but definitely needs the controls cleaned, and probably needs some of the capacitors replaced to bring it back up to factory spec. (There's also a slight hum coming from the transformer, but it currently hasn't had any effect on performance). I currently have no experience restoring audio gear, but am confident that I can change out the two dozen or so caps in this thing. I'll also have to buy some tools (namely a soldering iron) for this job, as I don't have any on hand. I understand the costs and risks of such a procedure, which tempts me to just splurge on a new integrated amp. I can only afford to spend around $350, so my options are kind of limited. From what I can tell my JVC outputs 40WPC at 8ohms and can drive anything as low as 4ohms at 0.007% distortion. Anything else new in my price range (like the entry-level Yamahas and Onkyos) have a little more wattage but also more harmonic distortion. To sum it up: Should I take the risk and repair the JVC or just buy an new amp? A new amp is more convenient and reliable, but the JVC just might sound better and ultimately be a good bit cheaper to fix up.
