Time for a new tube system.

Nice system. I used to own a pair of Cary 805s too. Can’t go wrong with Cary amps. But instead of the B&W speakers, I’d be inclined to put Devores with them, especially the new Gibbon X. Something to think about:

I agree with Mani-2, keep your amps and buy new speakers! Something a bit more sensitive? some horns maybe?

Dennis Had is no longer part of Cary and I would suggest searching the threads for customer experiences in the last few years. My vague impression is that some here posted disatisfaction with either the newer team/support or the newer gear. 

Agree w/posts that if you move up to the bigger B&Ws that those 211s might not be powerful enough to be a good match. I'd at least find some B&Ws who can confirm good results w/similar amps. 211s, 845s etc. can sound great, but they prefer a fairly efficient speaker with a relatively flat impedance curve ~8ohms+ in general. If somebody uses them with lower impedance speakers and gets good results, that would be good to post about. Cheers,

I recently tried out the ZOTL 40's. I wasn't sold.

@rothwea, matching speakers with amps is critical and not every pairing works.  What speakers did you try with the ZOTL40s?
