Ideas for Pre/Power $9000?

9K is a lot of money for an amp. Especially used. You can buy a great amp (or pre and power) and a pair of speakers for that.

I could go down a long list of recommendations for each but the easiest will be to use the 30-60 days return policies of Amazon, Crutchfield, safeandsoundhq, AudioAdvice, etc. and try a few things. 

there are many excellent Power Pre and Integrated amps at your price point. Your current speakers were excellent for the price...the new 6.2 version of them are on sale for about $600 pair including shipping, so not much value in selling yours...

I agree that there are many choices for either a pre/power combination or an integrated. That said, I believe if you are willing to spend 9K on amplification you aught to be thinking on spending about the same on each of speaker and source improvements down the road. If not I would advise rethinking allocation of funds across the board. 

I agree on system balance...I was merely stating the Elacs sale will be little help in getting better speakers to match the $9K electronics...and might be good in secondary system...and remain unsure why OP will not consider an integrated amp

I'm definitely reconsidering my allocation. Also keeping integrated amps on the table.
