I am somewhat new at home audio and any help would be most appreciated. My current set up consists of TSI 500s, a Pioneer SX-737 receiver, and a Pro-ject Debut Carbon turntable. I use this set up almost exclusively for listening to records. I live in a small apartment currently (expecting to move relatively soon to a house), and do not need major loudness. The 500s are obviously rated at 20-275 Watts and my Pioneer puts out 35-40 WPC. It gets plenty loud and sounds great to me, but admittedly, I do not have trained ears. I know my receiver is somewhat weak for the speakers and I plan on getting a more powerful one eventually, but I'm trying to see how urgent this is.
My question is, would it sound better if I had a more powerful receiver? Am I doing a disservice to my speakers? I would like to stick to vintage for many reasons, (price, phono input, look, etc). Am I possibly damaging my speakers because they are "less powered"?
Would it make a huge difference in sound quality if I upgraded to say, 60-100 WPC?
What are some recommendations for more powerful receivers that are somewhat readily available used?
Any help would be greatly appreciated! Thank you all so much.
