anyone here experience with Jeff Rowland Model 102

I have one for a while - one of the first built. It uses the same Bang and Olufsen modules (200ASC) as Bel Canto's S300 and M300. S300 is rated 300W at 4 Ohm because it is measured at 10% distortion. The module is identical. One of the S300 problems was resonating cabinet (improvement with antiresonant feet). Rowland is carved in the solid block of aluminium. Soundwise it is much better than my previous integrated (good one). It has a lot of energy and clarity in the mids and highs. Very clean sound. Bass control is very good and makes sound a little too lean. I changed speaker cables from thin sounding AQ Indigo to Acoustic Zen Satori shotgun and it improved lower midrange. Voices sound much fuller now. It is really analog amplifier with PWM output. It is based on Karsten Nielsen analog oscillator - I read a little a bit of his doctorate work on Internet (University of Denmark).

Is this the Model 102 you are referring to ?

Yes. It is Jeff Rowland Model 102 (2x100W@8Ohm, 2x200W@4Ohm). I bought it few months ago. Each amplifier board inside has its own compartment and has switching power supply built in - pretty much like two monoblocks with the common power cord. It has the smallest and the latest of B&O modules (200ASC). B&O was so impressed with Karsten Nielsen MS work that they sponsored his doctorate, gave him company stocks (first time to private person in over 70 years of B&O history) and created subsidary company ICEPower making him a president.

I mentioned S300 only because there are no reviews of the Rowland's 102 and Bel Canto S300 has at least two. I wonder if Rowland made any changes to factory modules since it normally voids B&O warranty. B&O does not sell them to public and the minimum quantity is one crate (790 units). They might have some design (changes) agreement. People at B&O are sound fanatics and probably squeezed all they could from the design. There are amps (Channel Island) based on Hypex modules available to public if you want to build yourself. Rowland has 5 years warranty.

Kijanki,

thanks for post.

out of curiosity, what pre-amp are you using with these ?

Are you using the balanced interconnect for these amps ?

What speakers have you driven them with ?

Appreciate your inputs.
