Although I'm not a Spectron owner, the following may be helpful.
My amps are NuForce Ref 9 V2 SE and I, like you, was in the market for a preamp to suit them.
I discussed this with Simon of Spectron since he was also involved with Joule-Electra. My goal was to find a tube preamp to compliment the Nu-Force, and provide enjoyment for many years. I want to get off the upgrade path and just enjoy my system. My bet was that the Spectron would benefit from a similar preamp.
Simon's excitement and information about the LA-300ME convinced me to give it a try.
The LA-300ME has been in my system for several months now and it never ceases to amaze with its musical presentation. No veils in front of the music, no artificiality, just a natural and very involving experience. Plenty of power and slam when called for, and also delicacy with detail, lots of detail. Combination of circuit design and very high end components makes this thing sing. This ranks with the best, no doubt. I have heard quite a few contenders at CES over the past 4 or 5 shows, (although this is not exactly an ideal place for critical listening you can tell the special from the not-so).
Hope you give the LA-300ME a listen to see how it performs with Spectron amps. Expect great things!
