Rowlands

Opposite to Jymc I have personally had 2 very positives experiences with Jeff Rowland's customer service:
1) they replaced me free of charge the control remote which falling on the floor was damaged
2) Jeff Rowland answered me personally an email with question about seeing up my system

concerning the 725 it has been just showed in Japan with Avalon Time
have a look here

I believe that the M725 pair shown at the Osaka show consisted of operational prototypes... Which means that they were sonically active, but were not yet production-level devices. G.

Just heard from JRDG.... M725 monos have been released and are shipping. US price is approximately $28K. Production level units should be listenable at CES 2012. G.

I've been using Rowland for my preamp and phono stages for 8 years now. A Synergy IIi and a Cadence phonostage.

The last two years I have been upticking the system and now have the Classe Cam 600's, the new B & W 802 Diamonds and a heavily modified VPI Aries and Sony 5400 SACD player with all the VSE mods you can throw at it. Cardas golden reference for the cables.

Pretty damn good system. But still maybe (and somewhat hard to believe) just a bit polite.

Enter the Rowland Criterion to replace the Synergy. Really amazing. Dynamics both large and small. Huge and deep soundstage. Deep controlled bass. The B&W's sparkle when the recording so provides and rock it when that's what fed. And I keep coming back to the dynamics. Not the polite Rowland sound I associate with my Synergy. Also, the Synergy was always mercilessly revealing. The Criterion keeps it musical regardless of what you feed it.

I am very very satisfied. Good for 8 more years.
