Audio Research LS3B or Classé Model Five

Hi everybody…

Once a year I use to modify one of my setups. This time I was thinking of replacing my preamp Classé Model Five by an Audio Research LSB3. I would loose a remote control feature in the trade but in this case I don’t care too much…
How do you compare these two preamps? Which one is best? (if so…). I tried to look over Internet but I just could figure that they were produced at the same period and cost quite the same.
By the way the amplifier connected to any of them will be an Audio Alchemy Om150.

Thanks for any opinions.
