You don't have to spend that kind of money to get comparable performance in terms of rumble and wow/flutter. In fact, you can probably do that well for 1/10 that much, but in hunting down turntable specs, which I admit to not having done in...um...a little while, I'm impressed by the lack of them. Turntable manufacturers not specifying the only thing they bring to the table...ok, sorry, that was bad...rumble and wow. Wow. That's not exactly full disclosure. I found one (VPI) that, if they spec rumble, it's a figure like "-80dB!", no reference specified, no weighting curve mentioned, but you know darn well there is one for that figure to be true.
Haven't bothered to look at specs for preamps, but I'll bet they're not quoted much either. We used to see everything spec'ed.
High-end or good vinyl setups were mentioned a couple of pages back.
Would the Pro-Ject Xtension 10 Evolution (€ 3000) qualify as high-end or at least as good?
Some measurements:
Bearing rumble, DIN B-weighted, into 47 kohm: -68 dB where 0 dB = 53 mVrms at 1 kHz
Wow and flutter: 0.09%
If we compare this to digital that's worse than ancient digital tech with ENOB below 13 bits.
That is without a preamp. I guess a high-end preamp isn't much cheaper is it? Maybe € 2k?
If designed properly it shouldn't add much distortion and noise (yeah, some high-end preamps are actually not designed properly).
Now this might sound outrageous, but a € 40 sansa clip can directly drive headphones, store gigabytes of lossless (if you wish) tracks, has less noise, no wow/flutter (jitter components down about -120 dB), higher dynamic range, lower crosstalk ...
