Music Reference vs. Quicksilver

Sounds like fun... I had EL34's for my RM9 and I used 6550's which I ultimately preferred because of the extra bass control and crytal clear highs. when you say RM9SE are you referring to the RM9 Mk2 which is a 125watt a channel amp versus the RM9 mk1. Keep in mind the(Roger's Tube company) RAM tubes are best for these amps because they DC stress test them because of the design Roger uses.

Also since you are using Cardas and if you find the amp to warm a step up to 6550 or KT88 (more delicate top with just as much bass as the 6550's) might be a better match then the EL34's (which are warm on top and rolled on the bottom. Even if the Merlin's are 8ohm, try the 4ohm taps also.... I've found with tube gear that I prefer odd taps on the back of tube gear.. 8ohm for 4ohm gear and 4ohm for 8ohm.. it's all about synergy..

Sounds like a lot of fun!

The Quickies will be much warmer and tubey in a classic since. The Music Reference will be more nuetral. It all depends on your current system,room,and music taste.

Cytocycle, it will be a "special edition" of the RM9 of which Roger made 19 of (he's kept one for himself) and sells for $8,000 - he has six left. I am running the 4ohm tap with my RM10 - "light loading" - seems to have slightly better bass, and also puts less stress on the tubes (Roger recommended it). Philefreak has it right.
