Hello all, my first post here for a while - couldn't say no boyzo's thrown gauntlet!
OK, I'll bite - Isobariks are wonderful. I have used them for several years now and have no desire to change them. Well, almost none (see below).
Bass: briks do bass like no other speaker I know (well, like no other speaker I can afford, at least! a used pair of DMS briks can be had for as little as ?300, at which price they are untouchable IMHO, providing you drive them properly). Deep, rich, authoritative. Nice.

Slightly off topic, I have now acquired a second pair of isobariks (much to my wife's annoyance, as she finds them even uglier than she finds me!). I couldn't resist them - heavily modified by Russ Andrews some years ago with reworked crossovers, fancy internal wiring and visaton ribbon tweeters in place of the original domes. I haven't the words to describe how good they are. All of the benefits of the originals (and some!) with none of the vices. The new pair are far easier to drive, with the sweetest top end and none of the midrange colouration of the originals. As an experiment, I even managed to get them to sing with a 40 wpc KT88 valve integrated. Try doing that with original briks (no, on second thoughts, don't. Could be messy). A Linn LK280 is my amp of choice and seems about ideal IMHO.
They came with a pair of Mr Andrews' custom built torlyte (whatever that is...) stands. I haven't done a direct comparison with the Linn open frame ones, but they certainly look nicer and don't sound obviously worse. In any case, humping briks around is for masochists and weightlifters only, so an A/B test won't be happening soon!

So, boyzo, I respectfully disagree with your assessment of Isobariks. Each to his own.
I'm off to spend an hour or two with Mahler, Miles Davis and Macallan. Fine company indeed.

Regards

Martin Very Happy

Oh Rhapsody!

I agree with all you say, but I'd rather be joined by a Laphroaig! Wink

And we thought that it was just the Hi-Fi nutters in Gloucestershire who liked single malts with their music... Surprised

I heard the isobariks in the 80s coupled to linn amps and LP12
in a Hi-Fi exhibition in London and I was amazed at the bass extension.

I am still keen to buy a pair and see what it sounds like at home,
hopefully it will blow me away.

Listening to all the different sounds/systems in a Hi-Fi exhibition is
an eye opener - some do sound aweful despite costing £000's

I always in the past found that Naim Electronics particularly suited Linn loudspeakers.
There was a signature from the amplification that reminded me of my Amcron DC150 and DC300 amplifiers.
Not subtle but they sure made the point!

We even ran a high quality disco (Discolord) using Amcron and Tannoy Ardens. The fill in loudspeakers were my poor suffering KEF 104aBs.
These were run by a heavily modified Radford HD250.

Only used in smal venues with a mediocum of care.
At one golf club the tweeters in the 104s caught fire and a few electrolytics in the crossover expoloded. Never made that mistake again. IDIOT!

Oh the lovely nostalgia indeed!
Ten Year After Stoned Henge, early Gong et al... BRILLIANT!!!

Very Happy Malcolm Jones has just made a couple of Cadenza "exhibition crossovers" for me.

I replied to his email where he mentioned their inefficiency with a picture of my pair of refugees from Abbey Road.

In his response he commented "enough to start a small fire".

No way Shocked , on mine the bridging switch is purely decorative Cool .

I recall a local Disco in the Midlands when I was 17 (31 years ago!) that ran using Amcrons and Tannoy speakers. Sounded quite phenomenal.


Good Grief!

Was the disco by any chance called "Disco Lord"?
The speakers Tannoy Ardens?

Also for near field addition when using split rooms KEF 104ab + modified Radford HD 250 amplifier?

Yup! We did a lot of shows in hotels and clubs with split venues.
The Tannoys and Amcron went to the dance floor, the KEFs were mainly used in bar or lounge areas at receptions and seldom cranked up.
However, after a venue at one of the local golf clubs the KEFs stopped working and one of the tweeters literaly went phut and caught fire!
YEs the fuses had been bypassed...

Upon opening the speakers the following day the crossovers were splattered all over inside of the cabinets, surprisingly one woofer survived. Very Happy
All was replaced by KEF at a cost and never used for that purpose ever again.
I made some special 'Fill In' monitors in custom cabinets using high efficiency multiple drivers.
