Dunlavy SCIV - What amp are you using?

I have SC-IIIA's and am running them with a current model Spectron Musician.

As I recall at various CES shows John used Spectron, Bel Canto (likely the SET 40), or Audio Research, depending on the year.

I'm more familiar with Duntech models but I believe the DAL designs presented an easier load, thus lower output and tube amps were better matches (than with Duntech models). But one thing to keep in mind with all of his designs, they are very revealing so quality of all upstream equipment is most important.

I always ran my SCIVs with tubes. I have used custom built 60 watt monos and Audio Research amplifiers with exceptional results. I personally have not used solid state, but I have heard SCIVs with Electrocompaniet and they sounded very good.

SET amplifiers? Maybe on simple music, but more complex music could be a problem.

I feed my Dunlavy SC4s with Air Tight ATM-3 monoblocks. Tubes used are Tesla E34Ls, Mullard "boxplate" 12au7s and Brimar longplate 12ax7s.

I have Dunlavy SC-IV Signatures (revised). I run them with a Bryston 4BST and a Audio Research LS3BR. The sources include a McCormack UDP-1 Deluxe. The interconnects are Kimber Heros and the speaker cable is Alpha Core Goertz. The sound is glorious, full, rich. It feels very complete to me in my large room. Hope this helps.
