Glad you picked up a pre-amp that you are happy with! I’ve had 3 Joule pre-amps, all supremely reliable. I let my LA 100 go and really wish I had kept it. It was magical with my music reference RM-10, a great little EL 84 amp that I can't imagine ever parting with. I currently have two Joule pre-amps.
I’ve also has 3 Joule amps and they were superb, but they can be a little noisy. I’m currently running as an amp a First Watt Sit-3, which is a great match for my Quintessence prototype Shadow speakers.
