I agree with everything Bresna said and would add, don’t be afraid of buying used. If you come across an integrated amp that’s 10 years old and doesn’t have a mark on it, it likely hasn’t been abused. I run a B&K amp and pre that are closing in on 30 years old with no problems at all. I had a tech check them out a couple of years ago and only minor adjustments were needed. You can find B&K equipment for short money, under $500 for 140-200 watts. But as already noted above, you’ll hardly ever use more than a few of those watts. A site you can find a lot of info on regarding older equipment is Audiokarma. Also try and find a reputable tech in your area, They’ll be able to help you determine what are good deals on Craig’s List, Letgo, Facebook Marketplace etc.
