Amp recommendation for Dunlavy SC V


I'm a proud new owner of a pair of Dunlavy SC V. I'm looking for recommendations on a good matching amplifier in the $3-4k range on the used market. Looking forward to your suggestions.

the Dunlavy woofers/cabinet enclosures are highly dampened and thus are very easily controlled by tubes or any amplifier.
I use the aforementioned VTL 450 Signature amps. Its a match made in Heaven. Especially after replacing the stock 12AT7 tubes with NOS Mullard M8162 tubes and the stock 6350 tubes with NOS Sylvania black plates. Magical!!!

For great control and full range depth, to stay in your price range, I have to recommend the Pass Labs X250. I had tried many amps, tube and solid state, and the Pass gear fit the bill the best for me. The most pleasing tube amps I had heard with my SC-5s were the Audio Research amps. Enough so that I bought the ARC, and them traded it in to buy the Pass instead. I have no regrets of having the Pass gear, even now (especially now) when I hear other amps. Best Regards.
