    The new Jeff Rowland 535 amp

    M535 is an amazing amp in its own right.... Nothing sterile or class-Diish in its tonal complexity, subtlety, broadness of frequency range, and musical immersion. I have run a pair in bridged mode for over a year, before taking delivery of the Daemon that I have been reviewing here on...

    Back to Jeff Rowland, now listening to Criterion and 825 :-)

    Hello shakti... Yes, I agree with you, the naming of the Rowland dedicated external power supply based on ultracapacitor to be PSU was not one of Jeff's best marketing decisions... Has apparently lead to some confusion as of the unique nature of the product. You are also correct that an M825...

    Back to Jeff Rowland, now listening to Criterion and 825 :-)

    Hello Shakti, a couple points... * are you operating Criterion's battery power supply, or are you staying with its AC supply? If your AC mains were a bit dirty/grungy, Criterion's driven by batteries will enhance the overall listening experience, versus its operations driven by its integrated...

    Rowland vs. Pass

    Woopsie... Thank you GSOphil for catching that... Looks like today my laptop is swallowing keystrokes. M735 power rating is 330W per channel... I have now corrected my original post. Regards, Guido

    Rowland vs. Pass

    The original class A/B Rowland M625 stereo and M725 monos are by now a little long in the tooth and have since been replaced by M625 S2 and M725 S2... M725 S2 is a withdrawn product as well, and has been replaced a couple of weeks ago by the new class A/B monos: M735. Here is what I know about...

    Jeff Rowland Daemon – Reviewing A Statement Superintegrated Amplifier

    In preparation for the next evaluation phase, I took down the system today at the 1135 hours mark. Seems evolution tapered off between 950 and 1000 hours. I reconfigured Daemon as follows: * Esoteric X-01 transport into Rowland Daemon DAC subsystem BNC via Cardas Clear Digital. * Rowland...

    Jeff Rowland Daemon – Reviewing A Statement Superintegrated Amplifier

    All, on Friday, while Daemon was playing the Post Horn movement of Mahler's 3rd Symphony around the 955 hours breakin mark, I realized that the critter was still making significant performance strides... In other words, music was even more luminous and magic than the day before. So, I decided...

    Jeff Rowland Daemon – Reviewing A Statement Superintegrated Amplifier

    Hello Sunil, thank you so much for chiming in! Are you still able to demo Daemon during these times of CUVIT? I know that before this virus, we could reach you at: Sunny Components West Covina California Phone: 626-966-6259 Phone 2: 626-966-2630 What is the best phone number or/and email...

    Jeff Rowland Daemon – Reviewing A Statement Superintegrated Amplifier

    Hello KeithR, I have had the original M625 in my system, which was very lovely, but not M625 S2... According to all reports I have read/heard, S2 is sonically quite enhanced over the original version. According to some, M625 S2 stereo and M725 monos might be the most refined pure power amps that...

    Jeff Rowland Daemon – Reviewing A Statement Superintegrated Amplifier

    Hello Site7000, thank you for chiming in... Are you also thinking that I should do the Daemon DAC comparison against the Rowland Aeris DAC+ PSU first? And the Daemon amplification stage against the Rowland M925 quad-chassis monoblocks later? For sure, both comparisons should yield some...

    Jeff Rowland Daemon – Reviewing A Statement Superintegrated Amplifier

    Daemon has crossed the 900 hours mark last midnight. I am now playing the fabulous performance of Mahler’s 3rd Symphony conducted by James Levine with the Chicago Symphony Orchestra (RCA RCD2-1757). Although the CD was produced in distant 1977, Daemon is making this performance so alive with...

    Cardas Audio cables

    Hello Jeffy, any cable with 50 hours on it is pretty young, and so is a Clear Reflection XLR. Initially, an ICS is likely to go through some seemingly bewildering tonal girations... Closed in one moment, and trebly or harsh the next. This is fully to be expected. My experience with my current...

    Cardas Audio cables

    All, I have been using a full loom of Cardas wires for a couple of years with fabulous results: Clear Beyond XL PCs on Rowland M925 monos, Rowland Aeris DAC + PSU; , Esoteric X-01 alternating between Clear and Clear Beyond XL Clear digital from X-01 to Aeris; Clear Reflection XLRs from Aeris to...

    Jeff Rowland Daemon – Reviewing A Statement Superintegrated Amplifier

    All, here is the promised update… At about the 630 hours mark, I seemed to hear a very slight increase in harmonics pressure in the treble region, accompanied by a hardening of transients, perhaps caused by minor intermodulation. The phenomenon seemed to persist for 36 to 48 hours, and then...

    Jeff Rowland Daemon – Reviewing A Statement Superintegrated Amplifier

    Hello Russ, while I missed RMAF the last few years, I remember the event fondly. Excellent rooms and not-quite-excellent rooms were equally memorable, if not quite for the same reasons. "Returning now to our "regularly scheduled programming", I am preparing a minor listening and system update...
