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.

I dont have experience with the turntables you mention, but I do use a Helius Omega on my Sota Cosmos IV. It is an exceptional arm. the Scorpio 4 uses similar bearing methods, so I would expect a similar sound. Their bearings are essentially 3 balls forming a base with one ball forming a point to make a triangle. supposed to provide the least friction in a fixed bearing.
I havent heard the AS TT but I have heard the P9 and Diva extensively. For me there is no contest, P9 is hands down better, especially with its RB1000 tonearm it is an amazing all rounder TT. In the Avid range it is the Volvere and beyond which really is top class. I would prefer the Volvere to P9. But Diva to my ears is purely a budget product which is made only to fill the gap.
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.
