Rowland 625 versus Audio Research DS450

I'm a big fan of Rowland Products. I heard the 625 at CES and was rather impressed by its huge solid soundstage, and the detailed yet mellifluous sound. I was rather depressed by the price tag. I was hoping it would be in Rowland 501 range.

I also heard the Audio Research DS450 with Magnepans at CES. While the sound was very relaxed and tube like, I didn't hear as much bass, as I would have liked. Perhaps it was the speakers or the recordings played?

I noticed both manufacturers avoided the term Class D or "Ice Module" like the plague. I think Class D has become a dirty word among some audiophiles...

Any other thoughts on how the sound of the Rowland 625 compares to Audio Research's DS450?

I would like to save up for one of them. The DS450 or even DS225 seem like they might be "better bang for the buck" (in relative terms). Appreciate your comments. Tks!

Audiozen, do you happen to know the list price per pair of the DS450M?. Hope ARC will feature them at the next RMAF in the Fall. I am rather intrigued! G.

Yes Guidocorona..they retail for $10K a pair. you can check out the amp's interior on Google images..I am leaning towards the AR's over the Spectron. The AR's have a much larger power supply and weigh just over 37 lbs each.

Very intriguing indeed AudioZen .... I really want to listen to these creatures at RMAF. I'll buzz the factory to find out if DS450M will be shown. G. to find out if they will be featured.

Optimus..looking more closely into the interior of the Audio Research DS 450M does not reveal very much make up such as extensive circuit boards and parts. A little on the skimpy side. A lot of caps and minimal board work. For $10K I wonder if one is paying more for a name than whats in the unit. Overall, the Bel Canto Reference 1000M MK.2 is the better value with more power at $ 6K a pair, and 500 watts rms. The Bel Canto peaks at 45 amperes and the Audio Research peaks at 35 amperes. The Bel Canto is on the warm side and I would think the AR as well since its voiced from their tube amps.

Audiozen, class D amps tend to achieve a high degree of circuit integration/miniaturization. While a very busy internal topology can yield a certain degree of pride of ownership all by itself, I much prefer to evaluate amps according to what they can do for me musically/sonically, rather than on the impressiveness of parts count.

The suggestion of evaluating DS450 against the well known and loved Bel canto ref1000M is an excellent one, as DS450's price tag fits somewhere in between Bel Canto REF1000M monos and Rowland M625 Stereo.

Specs alone suggest that ARC DS450, with 450W with 35A of peak current, might yield a larger stage and instrumental images than Rowland M625, which delivers a more modest 300W with a peak current of approx 20A. However, in the end, only sustained direct comparisons can tell the real story.
