Rowland Concerto integrated vs Rowland Capri & 102
Hi Rkny, PFC stands for Power Factor Correction. It is a miniaturized form of the line conditioning technology apparently used by power utility companies to control voltage fluctuation at the source. Jeff Rowland has scaled it down for use in high... 
Rowland Concerto integrated vs Rowland Capri & 102
The Capri has a much newer design than the pre in the concerto. In Capri JRDG applied some very high speed chips originally developed for the video industry. I had the Capri in my system last Monday and found it to be staggeringly musical and exte... 
Rowland 501 or Linn Klimax
I have a pair of Mahlers and have listened to 501s on Mahlers (not on my system). The 501s do a wonderful job of controlling the Mahlers on all frequency ranges and avoiding excesses. Dynamics is excellent overall. It is also fair to say that the ... 
VAC Ren II, VAC Phi, or ARC Ref 3?
Last Monday I had the opportunity of doing a comparative audition at some length of my Ref 3 with a JRDG Capri preamp on my system. My admittedly preliminary findings are intriguing, and can be read at:http://forum.audiogon.com/cgi-bin/fr.pl?aamps... 
ARC Ref 3, Rowland Concerto, or Capri line stage?
Hi Pinkus, I should add that the aforementioned pudding can be quite surprisingly delish! Will you A/B the Capri and the Synergy II? Will you add the PC1 to the Capri? Capri is based on chip technology originally created for fast video circuits, w... 
Balanced tube preamp for Class D amps
I auditioned the JRDG Capri driving a JRDG 312 on my system yesterday. The system was fully balanced using Audioquest Sky XLR ICs. I have posted my findings at:http://forum.audiogon.com/cgi-bin/fr.pl?aamps&1200110667&openmine&zzGuidoco... 
On The Feeding And Care Of Vienna Mahlers
Oh yes, subwoofers end up firing out with speakers just over 10ft apart center to center. 
ARC Ref 3, Rowland Concerto, or Capri line stage?
Yesterday I had Rod Thomson of Soundings Hifi (Denver, Co.) over at my place for a Master Set of my Vienna Mahler speakers, and he brought along a JRDG Capri for the ride. This was a unit without the external PC1 power factor Correction box. The r... 
On The Feeding And Care Of Vienna Mahlers
Ahem. . . what a coincidence MDHoover. . . just yesterday my Mahlers were professionally set up by Sumiko and by Rod Thomson of Soundings Hifi (of Denver, Co), 303-759-5505) using the Master Set iterative speaker placement methodology developed by... 
Audio Research ref3, vtl 7.5 vs FS paramount MKII
Hi Soundisntmusic, I do stand humbly corrected. I just checked with Bea at VTL and you are absolutely right. . . there is no such animal as a 6.5 Mk.2. the TL6.5 is in its original model. As I mentioned elsewhere, I have been very taken by the 6.5... 
Balanced tube preamp for Class D amps
John, pardon the ignorance. . . I do not know what SMPS may be.On the subject of tube preamps running hot. . . it depends what's in the power supply. . . my Audio Research has both a 6550C and a 6H30 in the power supply and runs quite hot, particu... 
Balanced tube preamp for Class D amps
John, tomorrow I will have at home a Rowland Capri to evaluate. Capri is a fully balanced linestage voiced for operation on the current JRDG class D amps. I will have the opportunity to connect it to a pair of NuForce monos among other amps. I wil... 
ARC Reference 3 preamp: tube character?
I agree with Chadnliz. . . CJ sound is musical and sweet; it has loads of the best attributes of tube designs without stereotypical flaws of woolliness in the nether regions or obvious lack of extension at the top. Furthermore CJ are truly single ... 
ARC Reference 3 preamp: tube character?
"Happy tube-tasting."Hmm, good tube! . . . (Satisfying 'Krunch!') . . . OOOOOuch!!!! 
ARC Reference 3 preamp: tube character?
I own a Ref 3 and concur with TVAD and Newbee. The design goals of Ref 3 -- which has been optimized for balanced operation -- seem to have been to be as even handed across the audible spectrum as possible without particular emphasis to any band. ...
