Lack of bass with SP-9 MK3

I've just acquired an AR SP-9 MK3 and my short-lived excitement quickly faded. While the depth and highs are crisp and more detailed than my old GTP-500II (Adcom), the lows are uneventful to say the least.

Granted the Adcom had the Contour enabled, this preamp's lows seem non-existent. I suppose there's a chance that I've been listening to exaggerated lows, but I've tried running various genres through the unit with same results. Is the unit faulty or will new valves fix the issue?

Any suggestions would be much appreciated!

fourrings00@yahoo.com, the input sensitivity of the amp is 1.7v.
On the preamp - CD Input to Main Output gain is 9db.

Could the out gain be a bit low for the preamp to drive your amp?

You can try switching your cd player from cd input to any available high-level input and you should get 21db of output gain. See how it sounds then.
