Ayre V-1X a killer amp

I have on loan a Ayre v1x driving my main panel Audio artistry Dvorak speakers and its a outstanding amp! I was very conted with Rowland m 2 but the Ayre was in every respect an better amp w outstanding dynamics, huge soundstage and fantastic microdetail presentation and a "tubelike" musicality. It has lifted the AA Dvorak to true high end performance. Unfortunatly the natural competion in this price range Rowland 10 or 12 are not availibly here in Scandinavia. Whats your opinion on the Ayre? I use Muse 3 preamp. Recommendations for preamps?
