Jeff Rowland Criterion vs Soulution 720

Hi Michael, I am very familiar with Rowland Criterion, own a unit and love it... But I am not familiar with Solution 720. However, it strikes me that Criterion is based on current Rowland architecture, while the M302 tends to show that it is 3 generations old, and may constitute a performance bottleneck... Are you sure you want to replace Criterion instead of M302? I am concerned that even if the Solution 720 were a substantial improvement over Criterion, M302 would remain a limiting factor in your total system performance.

Hi Guido!
Thank you very much for response. I thought about what you told and now I think that you probably are right. What amplifier you could recommend for replacement of JF302 in my system? The amplifiers well sounding with Magico Q3 are interesting.

Regards. Michael.

Hi Grayling, what is your budget for a replacement of the Rowland M302? Depending on your budget, I have a few ideas that are consistent with the power of M302 and with the kind of sound that I hope to get from an amplifier. Let me know!

About 30000$.

Hi Grayling, Rowland has a new stereo flagship amp, called Model 825, which fits your $30K budget. M825 is a two chassis SS amp with a total weight of $160. This means that the power supply is in a separate chassis. Power is 400W into 8 Ohms and 750W into 4 Ohms. The power supply appears to be a massive 2400W creature fed by its own PFC rectifier. M825 is the stereo version of the M925 monoblocks (which I have on order). It is my understanding that M925 and M825 are the very pinnacle of Jeff Rowland's design. M825 will start delivering in a couple of weeks. These devices are 3 major engineering generations past M302, and all reports I have heard this far indicate that unlike the old M302, their sound is extremely emotionally involving... I can't wait to have my own M925 pair delivered!

Saluti, Guido
