| Best amp to Partner with Jeff Rowland Criterion david, you may need an amp that yields more than 40 amps peak in balanced output mode, or more than 90 amps in the more common single ended output mode. With the new Rowland offerings, the 925 mono and the future 825 will likely do what you need, ... | |
| The New Jeff Rowland amplifiers ROCK Braz, considering that the circuit of Corus is largely derived from Criterion and is designed to yield similar performance at a lower price point, it is difficult for me to expect that Corus will exceed the performance of Criterion.On the subject ... | |
| Rowland model 5 vs Threshold S500 series II as 5Weseixas, in answer to your query on Rowland Model 7, I have owned Model 7 balanced monos from 1998 to 2008. I used them to drive a pair of Magnepan 3As and then briefly Vienna Mahlers V1.5. Model 7Ms have amazing power and authority, but they... | |
| Rowland model 5 vs Threshold S500 series II I looked at the JRDG Model 5 manual and found the following relevant information:Damping Factor Greater than 175, 20 Hz to 20 kHz, 8 ohms Greater than 60, 100 kHz, 8 ohms Output Current 40 amps peak, continuous 90 amps peak, 0.1 ohm, 20 msec, 1 kH... | |
| High Current SS amps with input impedance = 200K Mapman, IMO the BC 1000M (formerly 1000 Mk.2) are likely to occupy the current price/performance sweet spot of moderately priced 500W ICEPOWER gamut. While I have not been able to listen to W4S in the same system as BC, the general impression of m... | |
| New Rowland Criterion 2-chassis battery pre mark, Criterion uses large scale integration for its optical volume encoder, rather than discrete components. The dynamic range of the Criterion circuit is expected to be much wider than in previous JRDG preamplifiers, including that of various ve... | |
| New Rowland Criterion 2-chassis battery pre Mark, here is what I know about the control knob on Criterion.. . .The knob first of all has 2 distinct ways of operating. . .turning the knob adjusts volume for primary and secondary zones, right to left balance, input offsets, output offsets, me... | |
| New Rowland Criterion 2-chassis battery pre Yes, Audiophrenia being the most virulent known form of audiophilia nervosa. See:http://positive-feedback.com/Issue46/audiophrenia.htm | |
| Class D amps,bang for your buck ones Jtwrace, the ClassD amps look very interesting as they utilize some fairly novel technologies from TI. What will you be using for power supply. .. unless I'm wrong, they seem to require an external PS. Guido | |
| New Rowland Criterion 2-chassis battery pre Macro. . . I am glad that your case of audiophrenia is milder than most. . . may I ask you about PC-1. . . how has it affected 102 and Capri? I did prefer Capri without PC-1. G. | |
| New Rowland Criterion 2-chassis battery pre Braz, the 'device' is a power rectifier based on a technology called Active Power factor Correction (PFC), followed by a bank of capacitors for filtering furter the DC before the actual switch mode power supply. As far as I know, the technology is... | |
| Footers for Esoteric SA50 CD-SACD Player Chris, why not try some sorbothane disks under the standard footers. G. | |
| New Rowland Criterion 2-chassis battery pre Cappuccino, in that case the more recent 301 batches must be quite special. . . as much as I found the original 302 lacking, I am still in love with the 312. But I'm looking forward to hearing the newest 925 in my own system. . . probably Q2 or Q3... | |
| New Rowland Criterion 2-chassis battery pre Cappuccino, what design/sonic differences are there in the recent 301 amps vs the original series? I have heard that there some differences, but I do not know what these may be. Guido | |
| amp/preamp to complement Vienna Acoustics? Primare is another amp used frequently with the smaller Vienna Acoustics. . . not surprisingly, Primare used to be imported by Sumiko, still importing Vienna in the US. I have heard Baby Grands driven by Primare and the system was quite good, if j... |
