Joule Electra VZN100 Thoughts
I'm sure they sound glorious! I have one of their preamps and love it! Have you talked to Steve Leckrone of the Service Department who handles service for Joule? I assume you have. Joule Electra website link below (bottom of page): Joule Electra Service |
I can't help you in that I haven't ever owned them but I did have the opportunity to have a VZN 80 in my system for an extended period about 9-10 years ago, glorius indeed! Your concerns are the same as mine and a reason I ultimately decided against them, I was considering the VZN 100's, too big, too much heat from the VZN 80 as it was and I was concerned that the amount of heat generated would most probably shorten the life of the parts and there would be frequent service issues. I can't comment further on this since I've never owned them. I have read on these forums by an OTL manufacturer that a reason his company ruled against using the 6C33 tube was the amount of heat generated at the plate and the resultant fatigue that would result to the sockets. In other words, sockets should be replaced with the tube. Don't know about that for sure but it would certainly be a concern, especially coming from someone familiar. The bottom line is that there are tradeoffs for such a degree of magic the Joule provides and one has to ultimately decide whether it is worth it or not. I am sure if I had a dedicated listening space I would have seriously considered their purchase. It seems you have arrived at that point, especially with a toddler that has access which would be MY biggest concern. I hope it works out for you. There are other amps to consider, I have a Berning zh270 which I've owned for 10 years with not ONE issue including tube replacement and it is in regular use daily. It is no longer in production and I will say it doesn't have that harmonic envelope or the huge sound of the Joule. The two are quite different but IMHO the Berning is more natural to the source, OTL transparency, clarity, scale, speed and wonderful tonality. These amps have that uncanny ability to really separate instruments and voice in acoustic space which renders a realism to recorded music, as do all the OTLs I've listened to. The big deal with the ZOTL amps by Berning is that there is less heat and they are easier to place but they may not be your cup of tea. With a good source and well sorted out system they have a natural sound and presentation that I haven't heard bettered. Again taste would come into play and it might be too hard to walk away from the addictive sound of the Joule! You should at least listen to the newer zotl models if you haven't already. Different for sure but better, only you can decide. |
Thanks Tubegroover, for the response. The Joules have been solid except for just recently, a glowing red tube. I purchased 4 of the 6C33 NOS for under a $100 dollars including shipping from Russia so no complaints there. Waiting for arrival. I happen to have on loan an Almarro amp which incredibly and I mean incredibly, uses 2 6C33 tubes! So I borrowed one. Having great fun going between 2 sources, a Mac Mini using a Kora power supply running Audiovana and a CAPs server using a SoTM card running JRiver 18 both feeding my NAD M51 is it truly eye opening, stunning, whatever I can call it. What are the limits in this hobby? I may have to start burning incense. I will keep my eye out for the Berning. I may document the the Joules for a replacement of caps and new chassis. I do not own the "Musicwood" version. I'm pretty sure though, that with considerable effort, I can produce a very upscale chassis for these amps. The problem lies with the complete lack of support. With my former wiring gaf, all Jud wanted to do is sell me another set. And I did contact Steve but since I performed the replacement of the lamp cords that came originally with these amps, no one wants to touch them. Can't blame them really. It ended well, the cords are replaced, the sound even more open, crazy dynamics, and the hum diminished but certainly not gone. |
I owned the larger VZN 160's for a number of years. I put lots of hours on them and there were no service issues. They were built like a battleship, solid and always reliable. Their build quality/reliability certainly put another OTL vendor who's amps I was familiar with to shame. My VZN amps were very quiet. Wondering if the hum you mention is from a ground loop? Monoblocks are prone to amplifying hum caused by a ground loop. Have you explored this possibility? Also the support I received from Joule, whenever I had questions, was excellent. Per someone's mention that (and I summarize) "another .... OTL vendor due to the heat generated..... the sockets should be replaced with the tube." Do note that is not applicable to the Joule-Electra amps nor I suspect to Lamm or BAT amps. There was another OTL vendor who marketed 6c33c based OTL amps some years ago which, to be subtle, were a mess. Their problems, such as the socket issue you refer & which those other amps suffered from, were not inherent in the use of the 6c33c tube; they were due to incompetently designed/poorly built amps. |
