Any Jeff Rowland owners?

ICE Power modules (Class D audio amplifiers) used now by several amplifier's manufacturers, including high-end Anthem audio manufacturer (Anthem Statement M1 - monoblock power amplifier), are B&O's development babies.

This is strictly as pure info from B&O's own company's website, and nothing more to do with some of JR's amps than any related implementation that it has, or not: ICEpower ? Class D audio amplifiers ? Our History

And some additional information which some members might find educational: Attack of the Clone Amplifiers | Audioholics

- The Anthem (ex Sonic Frontiers) Statement M1 ($7,000/pair) is a Class-D amplifier.

- The Mark Levinson No.53 Reference (monoblock amp - $50,000/pair) is a Class-I (IPT - Interleaved Power Technology) amplifier.
 
Hi Davey, I thank you for the kind invite... If everything goes according to my evil skeemings, I might be able to travel to San Diego to present a paper at a conference in Mid March... In which case I accept and look very much forward... It will be my first opportunity of listening to the legendary M8!

Concerning current cabling adventures... I am working on some absolutely fascinating review projects... Hence my public silence on the subject. Unless I suffer from a sudden attack of Procrastinitis Furiosa, I will post an article on a complete loom of [redacted] by the end of February at the latest.

Hi Ralph (Kiwi), if you audition Continuum S2, do give it enough time in your system.... I am talking about several hundred hours of handling audio signals. Dealers are way too quick to declare that their gear is fully broken in. I have not tried CS2 in my system, but I suspect that 800 hours of break-in may not be an overestimate.

I did see and hear the 825s at RMAF. The Joseph Audio room with the Pearl 3s and the 825 was very musical. One of my top 10 rooms at the fest.

Also, I spent some time talking with Jeff Rowland. Really good guy.

I considered the 725s and the 825 for my Revel Salon 2s. Jeff uses the Salons in his shop. So this is a great match.

The best Class D amp I've heard by quite a bit. I think most people would be fooled.
 
Hi Davey, the power conversion/uplift leg of M825 and M925 is served by Ncore NC1200 modules, which run in class D... That is from 0.0W up to 400W/8 (M825) and 430W/8 (M925).

Guido, I have heard the newer generation of Jeff's work. I have also heard the Mola Mola amps. I still hear in the Mola Mola's the slight dryness and glare that I dislike in these type of amps ( class D). Please remember that i am coming from a more tube based system and I guess for me these types of distortion(s) ( in class D) are more irritating. Like I said before, class D is a non-starter for me, at least for now.

There is zero resemblance between the Mola Mola and Jeff's new amps. Nor any other Class D. Dry perhaps, more like half the info they should have. OTOH, the 8s were somewhat on the overly lush and soft side.
 
Hi Myles... Apologies, but "Dry perhaps, more like half the info they should have. has a dangling pronoun "they"subject... Are you referring to Mola-Mola or M825? "

Apologies. Mola Mola or the other Class D amplifiers I've heard with the exception of the new Rowlands.
 
Thank you Myles.... In fairness, Mola-Mola Kaluga had only about 200 hours on it... My experience is that the Ncore Nc1200 module and the accompanying SMPS1200/700 power supply require approximately 1000 hour to achieve best performance... On the other hand, Mola-Mola monoblocks and Rowland M825 stereo have a 2X pricepoint differential... 4x between Mola-Mola and M925 monos.... An overall performance difference between the Ncore-based amps of the two manufacturers would not be surprising.
 
JRDG system.....

I have had JRDG since the year he opened his doors (lots of Nelson Pass electronics as well) and very much enjoy my new JRDG electronics: Aeris DAC, Chorus preamp, 625 & soon to be 825.
All very musical to my ears & after 7 months "break in" sounding liquid & holographic. As it happens I have the Revel Salon's 2's & uber shotgun Cardas speaker cables JR use too. Very happy & likely my last system (give or take a few tweaks.) Enjoy all.
 
Hi Kiwi, Rowland uses Cardas for all internal wiring, for output terminals, and I believe also for the custom DC power cords and cpontrol cables between M825/M925 power supply chassis and audio chassis... Lately he has also used Cardas Clear / Clear beyond at shows etc... The combination seems to work extremely well for what I have been able to hear at RMAF in two different rooms, but I have not evaluated Cardas Clear/Beyond in my own system yet.

The Nordost large suite at RMAF (Blanca Peak, I believe) featured a complete loom of the new Valhalla 2 wires connecting and powering Rowland Aeris, Capri S2 (or was it Corus), M625, and a pair of Audio Physics speakers. All electronics were supported by Nordost Sort Kones, while the speakers were supported by the new Sort Footers designed for heavy speakers. The combination was absolutely wonderful.

I also am very fond of Shunyata CX and Z-tron wires, which I have used in the past on my own Capri (original), Criterion, M312, M625, and M725.

Sorry, I have never listened to Ansuz wires.

Saluti, Guido
