I decided to post my pre-amp update, because I had not been happy with my pre-amp choices with the RM-10. I purchased my RM-10 over a year ago without using it much with my 95db Tonian speakers as I needed a preamp with adjustable gain. I had almost given up and offered my MK II RM-10 for sale, but I found a perfect pre-amp for my system. Enter Decware's CSP Two Plus pre-amp.
Recently, I picked up a Decware CSP Two Plus manufactured earlier this year, and I found it was not fully broken in. After swapping stock tubes, vintage 6922s and a Mullard 5AR4 rectifier were inserted. As many RM-10 users know, this little gem is very fast and leans to the neutral side of the tube amp world. Decware products are also known for speed and a neutral presentation, and the CSP II is no exception. Together, there is the synergy that I have been searching. Yes, the RM-10 and CSP2+ work very well together.
What I really like about the CSP2+ is it has both input and output volume controls for each channel. This really gives me the control I need when working with a low output MC when listening to LPs The subwoofer jack is also a plus. Since the Decware products come standard with walnut bases the RM10 and CSP2+ match very well in my audio rack.
Oh I forget, the CSP2+ also works very well with my MR245.1 amp. Many have not heard Roger's 245.1 amps and they are no longer available. Like the RM-10, the MR245.1 (45 tube) amp is very fast. The midrange and treble with this 4 watt tube amp are strong points; however, a subwoofer is needed for bass.
