I've got the PoJect Phono SE. Bought it about a year ago and have it plumbed into my Cyrus setup. It's a fine middle of the range turntable, and like anything else hi-fi the law of diminishing returns will apply, i.e quality improves linearly while price increases exponentially.
It's fine for me reliving my mis-spent "yoof" listening to 70s and 80s heavy metal, but serious vinyl buffs would almost certainly find fault.
When I bought it I went "one step up" on the Ortofon cartridge (it's a black one but that's about all I remember). Cost me about 20 quid extra.
The only criticsms I have of the ProJect is that the unit comes with hard wired in phono leads, which look a bit on the Currys side of the price / quality balance (I would have like to use decent interconnects like Chord Chameleons) and the volume isn't as high as the rest of the line inputs, so I have to adjust the volume (thank heavens for the remote, eh?).
But I have to ask, if you have a phono stage in your amplifier, and it's working okay, why bother?
