Should I Repair a Plinius 8150 ?

It's a hobby and there's not a hobby in the world that doesn't cost money and makes none. Have it repaired and enjoy it. It's served you well. Give back.

If the "tech" is Vince Galbo of Advanced Audio, I would'nt hesitate. He performed an amazing upgrade on my Plinius M-16 preamp. He undestands Plinius equipment like no other, and keeps you in the loop throughout the process.

If you love the Plinius, the answer is easy. If not, it might be a good opportunity for a change. From a pure cost standpoint I would consider what you might get for it on the used market as is, add that amount to the cost of repair, and see if there is a newer integrated you could get for the total amount that you'd be happy with. For example, if you got $300 for it, a newer integrated in the ~$1100-$1200 range would make sense financially. On the used market, you can get a lot of amp for that amount.

I think it would be really hard to find something as lovely as that amp for $750. I do this: I flip a coin and if the coin says the same as my gut feeling then it validates me and if the coin says something opposite to what I felt I wanted to do it highlights my inner thoughts about the repair / upgrade whatever.

As mentioned already; I'd shop around and see if you can't find a better price. Plinius makes a very good product.
