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    The original class A/B Rowland M625 stereo and M725 monos are by now a little long in the tooth and have since been replaced by M625 S2 and M725 S2... M725 S2 is a withdrawn product as well, and has been replaced a couple of weeks ago by the new class A/B monos: M735.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

    Jeff Rowland Daemon – Reviewing A Statement Superintegrated Amplifier

    Hi all, I replaced all six sections of my scribblings with revised versions... Removed a bunch of typos; streamlined some clunky text; and corrected wording about phono stage... Daemon actually comes standard with the HP Phono stage for $43,840, while the phonoless stripped down version is...

    Jeff Rowland Daemon – Reviewing A Statement Superintegrated Amplifier

    Hello KeithR, unfortunately I can't help you about digital power amplifiers. I do not think I ever heard one. As for the analog class D M201, it was a very early device, and it showed its technological immaturity. I am not surprised you did not keep it. I auditioned it a few times, and never...

    Jeff Rowland Daemon – Reviewing A Statement Superintegrated Amplifier

    Hello RussR, glad you are enjoying my scribblings.... Much more of them to come during the next several weeks :) I vaguely remember that the Daemon used at RMAF in 2015 was not only factory-fresh with little or no break-in, but may have been a relatively early prototype, rather than the...

    Jeff Rowland Daemon – Reviewing A Statement Superintegrated Amplifier

    Thank you Carlos for expressing your concerns. As I already mentioned in the diary, which BTW I had to split into six post not to exceed the 10K character limit per post, the Daemon in my system is a review unit. I did not mean this scribbling project of mine to feel info-mercialish. My...

    Jeff Rowland Daemon – Reviewing A Statement Superintegrated Amplifier

    Hello KeithR, Skepticism is a healthy thing of course. And DarTZeel does make superfine products in its own right, which I always greatly enjoyed listening at RMAF. Actually, Daemon does sell usually complete with the High Performance Phono sub-system pre-installed. So, more than the phono...

    Jeff Rowland Daemon – Reviewing A Statement Superintegrated Amplifier

    Hello Steve, yes... So far so good, thank goodness... There is still relatively little COVIT19 here in SC... Yet, I live largely sequestered, just in case. More time to dedicate to this scribbling project of mine :) ... And, I'm real happy to be back on WBF!!! Saluti, Guido

    Jeff Rowland Daemon – Reviewing A Statement Superintegrated Amplifier

    Hello Lagonda, I admit of being rather methodical and plodding. Until Daemon has completely stabilized, it is a moving target... A comparison with my separates would not be particularly meaningful at this time. Once Break-in is largely complete, sometimes past the 1K hours mark, I am planning...

    Jeff Rowland Continuum Series 2 Integrated Amplifier

    While I truly loved what I heard from Continuum S2 at RMAF, I admit that I have been until now a die-hard lover of separates, and of monoblocks to boot. Since 2013, my Rowland M925 monoblocks have been making fantastic music without a glitch. For the last few years, I have been feeding Them...

    Rowland M925 - The amplifier saga continues

    All, is there life after M925? Yes, my beloved Rowland M925 monoblocks have been making fantastic music without a glitch since May 2013. For the last few years, I have been feeding Them directly from a Rowland Aeris DAC, this augmented by the Rowland PSU ultra-capacitor-based external power...

    Rowland M925 monoblock amplifiers -- Break-in Notes

    All, my beloved Rowland M925 monoblocks have been making fantastic music without a glitch since May 2013. For the last few years, I have been feeding Them directly from a Rowland Aeris DAC, this augmented by the Rowland PSU ultra-capacitor-based external power supply. Yet, I have been wondering...

    Jeff Rowland Daemon – Reviewing A Statement Superintegrated Amplifier

    5. Thoughts And Photos Daemon has been playing 24/7 since unboxing… It continues to be barely lukewarm to the touch. Surface temperature feels the same across the top plate, front plate, and side cooling fins. This bespeaks the 1500W power-house’s superior energy efficiency, and excellent heat...

    Jeff Rowland Daemon – Reviewing A Statement Superintegrated Amplifier

    4. Music And Sound – Part Two During the first 24 to 48 hours of operation, the integrated felt somewhat shy of power reserve and authority. Center-stage was actually affected by a marginal image suck-out. Things evolved rather rapidly, al be it with cyclical fluctuations. Thus, around the 100...

    Jeff Rowland Daemon – Reviewing A Statement Superintegrated Amplifier

    3. Music And Sound – Part One Daemon's output power rating of 1500W/8 and 2500W/4 per channel exceeds a pair of M925 monoblocks by a factor slightly greater than 3. By the time of this writing, I can already tell that music flows with even greater ease than from my M925 pair. But this...

    2. Physical Description Before we plunge into the more or less chronological narrative of my break-in adventure, here is some more information about this power-beast: Daemon is hardly a featherweight: at 99LBS in its machined aircraft-grade Aluminum birthday-suit, the single-chassis looks...
