As you know a high quality stereo system is expensive, But if your system was say 90% of high quality you would certainly enjoy it. Listed are a few items that way outperform their price point. I list these so you can get quality without breaking the bank. It is much better today vs 10 years ago for a deal.
AMPLIFIER
Everyone believes tube amp are the best and they are. But vintage are not that good in the under $1K category and I owned a lot. Rebuilt them as well so heard about everything. A Nobsound 300Wx2 amp that is $189 new will outperform up to $1K vintage tube amps. .It has tone controls and phono input. About 40 watts RMS per channel. It does not need an op-amp upgrade either.
TURNTABLE
I owned a few Turntables. Best was Garrard 401. A good TT is a Project Debut Carbon. New is $1K and used $750. I compared to a Pioneer PL-30-K and I did not hear much difference. I was using an AT VM-95ML. The Pioneer is under $300.
CARTRIDGE
I compared an Audio Technica VM-95ML to a lowly AT3600L at $20 new. Not a lot of difference but treble was smoother with the VM-95ML. However, you can live with the cheap cartridge. It is lively.
