I bought one of these, they're not terribly expensive. My goal is vertical biamping of ADS L-1290/II speakers.
This thread isn't about those speakers, we have other threads about them. It's about the quality, my subjective impressions of the sound quality, of the Rolls Xover.
I'm integrating this little xover into a John Curl designed, Parasound system. I have a P/LD-1100 pre-amp, and two HCA-750A amps.
My source is all digital at the present time. I have a PC with a Paul Pang v2 card in it. A Pangea USB cable goes to a Singxer F-1, then a Belkin Pure AV digital coax cable goes to a MusicHall 25.3 DAC. The DAC has an upgraded buffer tube (Mullard CV2493).
So is the little Rolls up to the task ? Let's have a look.
First, it's made in the USA and it has a steel case. Surprising heft for its size.
The chassis bottom is also steel, and the edges of the PC board sit on the folded edges of the bottom pan. Nice engineering.
The pots were suspect by others in the Amazon reviews, because the center detent on the high gain is not exactly at 12 o'clock. My unit has the same quirk. However, the pots have a nice feel, and they are open to allow cleaning. The logo on the pots is a C with a reverse C nestled into it. I don't recognize the brand, but they rotate firm and smooth.
