Basis Ovation / 2500 vs Sota Cosmos IV

Thanks to everyone who posted thus far.

I've had two Sota tables since 1983. First a Sapphire, then a Sota Star Sapphire (vacuum) that I bought when I worked at a high end retailer. I've always liked Sota's but it might be time for change. A friend of mine has a Debut that is really nice. I know the Debut could most likely be a better (and probably is) a better table than the Cosmos.

I have noticed some speed instability with the Star I have now on some piano passages. From what I've read and heard the Basis does not have that problem and the newest Cosmos does not either.

A little "dark" sounding is fine with me as I listen to a lot of pop and rock recordings that are usually bright anyway. I also listen to jazz, blues, and just a little classical.

I never play 45's so changing speeds is not a big deal to me.

Does anyone know if the armboards between the Ovation and the Debut interchange ?

The rest of the system is a Classe Six pre, Levinson 23.5 power, and Revel F53 speakers along with two Revel 12" subs.

Thanks again

Rcprince- thanks for your comments.

Has anyone had the chance or know how a newer Basis table (say a 2001, 2500, 2800) would compare to a Ovation ?

Thanks in advance

Thanks to all who have responded !

Basis Debut vacuum owners: Has anyone had any issues with the vacuum system ? Out seal failures ? Vacuum pump failures or noise ?

Thanks
