Rega P25, would it sound better than my CDP?

I don't think my comment was out of place. And I'm not saying Regas are pitch perfect, because they aren't.

But even if the test you propose makes the Rega sound sluggish compared to the seedee, that is not what you said. You said

>music will sound sluggish and percussion instruments will not sound crisp and fast.<

You didn't say

the music on this record as compared to the seedee

What I'm saying is that sluggish is not how I would describe the Rega. And it is the first time I have ever heard it described as such. You are entitled to your opinion. And I think I remember you as being a Rega basher from posts on the Asylum. No harm, it that's how you perceive it. But my point is you are in the minority with that perception.

Superior sound? Dunno. Most assuredly it will sound different. However, the Rega arm and Benz cartridge are basically entry level analog. The actual sound may not match your expectations.

it won't necc sound better, but you'll have more fun listening to it.

My Rega P25 with a Dynavector 17D Karat, sounded better than my Levinson 37 transport and Chord DAC 64. Your mileage may vary.

If you have an extensive LP collection I would say go for it, but you might do better with a Nottingham Analogue deck at that price.

If you have no LPs I'd say save your money and get a better CD player.

The difference in sound quality between CD and LP is significantly less than the variance in recording and mastering quality IMO.
