AS Challenger mk 2 vs. Avid Diva 2 sp vs. Rega P9


After many hours of research i've narrowed down my next turntable to...
1-Acoustic Signature Challenger mk 2
2-Avid Diva 2 sp
3-Rega P9

Have heard the P9 mulitple times and was impressed. Frequency extension and bass slam appear to be a minor weakness with the P9. Have never heard the Diva 2 sp or any AS models. From what I have read the Avid/AS excel where the Rega P9 is deficient. I would appreciate any comments from current/previous owners or those that have had experience with these 3 turntables. FWIW i'm considering a Helius Scorpio 4 or OL Encounter tonearm on the Avid/AS, cartridge preference is a ZYX R100 for all 3.

Pani/Manitunc-Thx for your response. The Diva 2 i'm considering is the SP model. Which has a 6.3kg platter vs. 2.5kg it also adds speed control. I would never expect a basic Diva to outperform a P9.
You may want to consider the Rega RP8! I think it will soon be available, if not already. I also recommend the Well Tempered Amadeus, as another option. I am buying a TT for a second system, and have settled on the standard Amadeus.
Another interesting table that's not too expensive is the Merrill REAL table. The only one I know from experience is the Amadeus,the GTA would fall in to your general price range
Roscoeiii-Having read your other posts I assume you own the Townshend Rock 7? Is it true that the standard motor is very power cord sensitive? Does the standard motor use a wall wart as a power supply? These possible issues had swayed me away from the Rock 7, since the optional power supply/dc motor which addresses these issues costs an additional $1900.
Dayglow- It sounds like you may have read it, but there is an A/S review of the Rock 7. It's written by Robert Greene, and he makes comparisons between the Rock and the Amadeus. What I drew from the review was he seemed to like the Rock a bit better. He also thinks they are cut from a very similar sonic cloth. Perhaps both tables using damping, may contribute to their sonic similarities. Again, just one persons view, but an interesting read. That review comes up if you google Townshend rock 7. My thought on the Rega's is the company seems to be implementing changes to their newer models. The RP3, RP6, and RP8, I believe would be those latest models.
