Strength:
Everything
Weakness:
Remote Control What can I say ? It is just one of the best preamp I ever listened to. Me and my friends we have done heavy comparisons. We have no doubts - this Preamp gives you the soul of the music.

Strength:
Sounds more "real" than any other per-amp I have ever heard. Will even make a high-quality solid state power amp virtually indistinguishable from a high quality tube power amp with very good speakers. Has a remote control which is very handy.
Weakness:
Quite expensive - until you see the power supplies and build quality. This review is for the LAP 150, which is the LA 150 pre-amp with the OPS 1 tube phone pre-amp built in. In order to accomodate the extra phono circuitry of the OPS 1(also available as a separate stand-alone unit), the LAP 150 has a large and heavy separate tube power supply unit that connects to the LAP 150 via a umbilical cord. I listen to a lot of vinyl, and the LAP 150 replaced a Hovland HP100 with phono which I had used for 3 years. The dealer was nice enough to let me demo the Joule with the Hovland for two weeks, so I could do detailed comparisons before springing for the hefty purchase price of the Joule. To begin, the Hovland HP100 was -and is - a wonderful pre-amp - but - the Joule LAP 150 is a very significant step better. How? (See my review of the Joule Electra VSN 100 Marquis OTL power amps). The Joule will do "what you are listening to is real" and "you are there in the room with the performers" better than the Hovland. As I indicated in my VSN 100 amp review, I use a set of Bryston 7B SST solid state power amps as a back up, and the Joule LAP 150 even makes the Bryston solid state amps sound as "liquid and detailed" as the Hovland HP 100 pre-amp did driving a set of Cary CAD 300SE LX20 tube amps through the same (Merlin VSM/M) speakers. An amazing accomplishment for folks who want the tube "you are there" sense of reality, but want to go with a solid state power amp! (Note, the Bryston 7B's do not sound as "real" as the Joule LAP 150 driving a pair of Joule VSN 100 Marquis OTL tube amps - that combination seems to be in a league of its own). How does Joule do it? I am not entirely sure, but two guesses are (1) power supplies and (2) build quality. The Joule LAP 150 has a power supply with separate feeds to specific parts of the pre-amp and phone sections that puts many power amps to shame, and tube regulated to boot. This seems to give the sound an effortless dynamic "jump" or startle factor while remaining extremely low in perceived distortion. Second, if you take a peek inside, Jud Barber does build quality that has to be seen to be believed - like double sets of contacts for each switching contact in the source selector to reduce contact distortions, battery DC supply voltage for the pre-amp tube bias current, etc. He also uses exotic Russian tubes (now more widely available) that can greatly outperform the classic AU7X and 12AX7,s that most other tube per-amps use.
