WARNING - I'M BIASED AGAINST VINYL!
QUOTE
Would it be a better idea to invest in a strong cartridge and a decent phono preamp? Or the other way around, a decent cartridge and a strong phono preamp?
For example a $200 or $300 cartridge from Audio Technica or Ortofon, etc. and a Rega Fono Mini Phono Preamp ($145)?
Personally, I wouldn't spend $300 on a cartridge! You're getting well beyond the point where the cartridge is the weak link. No matter how good the cartridge, you're still going to get vinyl noise and perhaps preamp noise.
Perhaps I'd have a different attitude if I had a large record collection in excellent condition, and if I was in a stronger financial positon where $300 was no big deal... But, I don't know... To me, it doesn't make a lot of sense to spend a lot of money for an analog set-up that still sounds worse (more noisy) than a CD.
Right now, I'm in the middle of a vinyl-to-digital transfer. (It's a 1976 recording in poor condition, and a CD was never released.) I've spent a few evenings cleaning-up the "snap", "crackle", and "pop", and I'm not done with the 1st side yet. When I'm done with that, I'm going to add some high-end boost, because the highs are badly attenuated on this particular recording. With such poor "frequency response" on the record, a better cartridge would still leave you with poor sound quality, even if the record was in like-new condition. When I'm done, the most offensive defects will be removed or reduced, but there will still be some remaining noise, and I won't have "CD quality".
I've never owned a really good preamp, and I could always hear hiss with the volume turned-up. I don't know if a better preamp would push the noise below audibility. I'm a tube skeptic.
It's more difficult and expensive to build a good tube amp than to build a good solid state preamp. And, tubes deteriorate and eventually die. But to be fair, some people think tubes sound better, and some pro recording engineers prefer tube microphone preamps.
