Jeff Rowland's Continumm
Jeff Rowland has finally updated its web site with a page dedicated to the new Continuum 250 and 500. Here it is:http://jeffrowland.com/Continuum.htmAnd here are some specs for all lazybugs (grins!):* * * *Specs: 250 Version / 500 Version Output P... 
Audio Research REF 3
Yes, Ref 3 is much more dynamic and quieter than LS25 Mk2. The old ARC silver-gray sheen is gone completely. The sound is very focused, has loads more authority, and harmonic complexity than LS25 Mk.2. . . . but it is not at all leaner. On the oth... 
Audio Research REF 3
I have owned a Ref 3 for a couple of years. The lifespan estimates made by ARC for all tubes as applied in this device are extremely optimistic. The 6550C shows some sag at 900 hrs and usually needs to be replaced by 1100. In my unit the driver tu... 
Review: Sumiko Speaker Set Speaker
My Mahlers were professionally set up by Rod Tomson of Soundings. . . and the resulting enhancement was nothing short of bleedin' remarkable! And the funny thing is that all he used as measuring instruments were our collective ears and a simple le... 
ARC Ref 3: Tung-Sol 6550 in power supply?
What can I say Rodman. . . I have listened and done live unamplified, acoustic music for almost 50 years and still have no idea what many are talking about when the whole issue of the realism of tube bloom arises. . . I'll try to listen to live mu... 
ARC Ref 3: Tung-Sol 6550 in power supply?
Hi dave,how about an early Jan 2008 NOS version of the TI Burr Brown OPA1632 differentially balanced OP amps in the linestage section? I heard from a bunch of wild internet chipheads that it readily trounces the 2008 post march 31st current produc... 
ARC Ref 3: Tung-Sol 6550 in power supply?
Thank you Rodman. As you know, I can only report what my ears tell me. And I try to report my observations in as descriptive manner as possible, so that other Audiogoners can draw their conclusions, based on my observations, not so much on my 'jud...

"inane attacks"Huh? did I? Guido not a listener? Truly? [now scratching head furiously] and how else would I evaluate equipment. . . by looking at it mayhaps? ]chuckles] 
Jeff Rowland Capri preamp
Hi again Clio, interesting you use VAC: Capri has same output impedance of 40Ohms SE and 80Ohms balanced as VAC Ren II pre. I suspect impedance match will be quite good. What I am not sure is if VAC is differentially balanced or simply has XLR inp... 
Jeff Rowland Capri preamp
Clio09, I am even more conservative than Dave about Capri's breakin. . . mine has continued to sweeten and open up for over 3 months. . . I estimate that breakin time may be as much as 800 hrs before Capri stabilizes. after 100 or 150 hrs Capri wi...

Thank you Ethannnn, info very much appreciated. Guido 
ARC Ref 3: Tung-Sol 6550 in power supply?
That's very interesting Ethannnn. Would you care characterizing in some detail the sonic results of the various tubes you tried on Ref 3? Thanks, G. 
ARC Ref 3: Tung-Sol 6550 in power supply?
Elberoth2, I would give the Tungsol a couple hundred hours of playing time at various gain levels to stabilize. G. 
Should I upgrade from BAT31se to AudioResearchRef3
I concur with Doc on Ref 3 being a wonderful linestage. However, if you are a lover of 'bloom', the Ref 3 may not be necessarily the device for you. Overall, it is more linear, tighter, and somewhat less bloomy than many tube line stages on the ma...

Bart, if you have some experience with tube rolling for Ref 3 that we have not covered yet, please enlighten us. G. Ref 3
