I had been happy with Silbatone fitted We 300b made in 40's for 10 years in small space.(4m wide 6m deep 2.5 m high)

But after moving to larger listening room, it does not have enough headroom to drive Lansche 4.1.

I am looking for horn speaker above 105 db/w to work with Silbatone.
Sounds fun! Will be curious to learn about what you choose :)

my guess is its just a special edition Rick sells - sorta like Cary did with the F1 editions for Upscale Audio
You are correct. IIRC the output tube is made for Rick also.


To be clear, this amp is not an OTL. The patent clearly shows an output transformer (air core, but a transformer nonetheless) and a semiconductor circuit, both of which are used for impedance matching. OTLs have neither; the tubes drive the speaker directly.

I had Jadis 30,80,200 and 500

500 was the worst.I used with Soundlab A1 but sound was too full in mid bass and roll off
Was in 1992,also in other system of my friend with Apogee Diva was no good

I don't suggest,fantastic look but i suggest to try before to buy

Ja500 had worked wonder with B&W Notilus 801 with 15 inch woofers.

Synergy between amp and speaker is important.

I had used DCS Elgar direct without any pre amp.

Without too much heat out of it, i would have lived with it few more years.

Was 30 the best, and the 80?

That's not surprising. ESLs have an entirely different operating principle and a voltage source amplifier isn't always the best way to drive them.

The Soundlab A1 of the early 90's probably still had the wood frame and the equality spaced ribs - it could easily sound too full in the mid bass. Things improved significantly when they introduced the distributed bass resonance structure.

The A1's had several versions of the crossover along the years (referred as backplates), some optimized for solid state, others also for tubes. Current PX models with the Torroid II can be used with either type of amplifier with success - the VTL Siegfried II or the Lamm M1.2 are an excellent match. The A1 crossover has adjustments for bass, medium and treble.

Sad to say I have to agree with G here--having owned( struggled ) with 7Jadis units both Power /Pre and Digital since the early 90s'-

and would advise all prospective buyers to tread carefully-I had transformer failures/ Amps shutting down plus lousy service and backup.

I too drove Soundlab A1's and A3's-similar sonics as G above experienced even after the Transformer mods--Good but not great combo:(

The 150 monos ( my last )tho showed promise into my Avalon Ascent IIs--remember Winston Ma liked these as well earlier on!

Jadis is an excellent product that has seemingly suffered from adverse agents and tech backup with all except possibly the Asian and UK regions--

but need the entire network to maintain and service --I sincerely hope they can progress today with this in mind.

I had A1 driven with Ja 500 but cut at 100 hz and sub Mono Soundlab B1 driven by 2 pair bridged Mark Levinson N20,400 watt bridge instead 100 watt with crossover ML LNC 2 mono
I had Pre ML 6 B and N 20 mono and asked to Mark Glazier of ML to do also for me LNC2 mono and they did
Could be the only one made because always did stereo

There are two interesting 80K$ tube amps on sale at Audiogon.

View attachment 66011

https://www.audiogon.com/listings/lis9jhj0-david-berning-co-211-845-otl-tube

The first one is David Berning OTL design with output of 60 Watts.

it looks beautiful. But I had never used OTL amp yet.

I am curious how it sounds with high efficiency speaker.

The second one is Jadis JA800 with 6 pieces and 400watts.

I had used JA500 (only 4 pieces with 350 Watts) from 2000 to 2002 to drive B&W Notilus 801 with utmost authority and unbelievable slam.

It was kind of lifetime experience to own this beautiful and overbearing monster.

But I could not use it during summer time in modest size room.

Thus I let it go and got Silbatone 300B SET amp to drive efficient full range speaker.

350 Watt to 8 Watt

If you have money or hit the Jackpot, which one will you go for?

I think you made the right choice to go with the Silbatone SET and Lansche speakers...I am sure that is a great sounding combo.

After having lived with JA500 for 2 years, i may not go back to it due to too much heat out of it.

But I would like to have a chance to audition David Berning OTL some day.
THe Berning is not a true OTL, FWIW.

Yes, and I found that my STAX ELS F-81s I had back in the day worked wonders with an amp that sounded too warm and mushy into other speakers I tried it on (Golden Tube Audio SE100, which was not a SET despite the SE in the name). It did sound pretty good on the Infinity IRS Beta panels though (no bass of course). That STAX/GTA combo was spooky good. They also sounded very good with a KR Audio VA350i.
