I own the Merlin VSM Milleniums, and have a Joule Electra OTL. This combination is magical. I'm sure the Sonus Faber is a great speaker, but I would think that there might be a better amp out there for them than an OTL. On the other hand, the Merlins were voiced using the amp that you own. Anyone with any experience in this hobby knows that amplifier/speaker synergy is especially important in obtaining the best possible results from your speakers. You already have 1/2 of the recipe. Unless you want to change amplifiers, it's an easy choice.
Sonus Farber Guarneri vs Merlin VSM
Looking to complete a 2 channel system consisting of a Theta front end transport and DAC, and Joule Electra OTL monoblocks. Any other suggestions are welcome but my spending limit is about 4-5000. I am having some trouble finding both of these speakers to audition in my home so I would like to here from as many of you as possible before I decide on a speaker.
