I had dinner with Mike Harvey from Octave this weekend. Mike acquired the intellectual rights, tooling, drawings and jigs needed to manufacture the S2's. I believe that newly manufactured S2's will be available very soon. Mike is sufficiently thoroug...

[quote user="Dominic"]Here's a threeway with the BMS coax like in your orpheans nested in what i think is a 80hz horn which is driven by 2x15"sI'm not sure how well the time alignment works. I think the woofers are a bit too far back.in any case: [/q...

Coincidentally, yesterday (14th Feb in this part of the world) -- a timely coincidence as I only read the posts today.A friend constructed a temporary 150Hz tractrix out of hard paper -- a 12hedron. This is not about the sound etc, the horn served fo...

There is a live recording (in stereo) of Beet 5th piano with Gieseking/Rother/Greater Orch of the 3rd Reich. The concert took place in 1944 and, allegedly, Hitler was present. The conductor is reported as Rother -- but there's a rumour (urban le...

If I may add, from experience, following and including Romy's post above:1) In cases of established incompatibility with a average power SET, more output energy (55W), will not completely clear the above 2) and esp. make 3) less "muddy" or ...

[quote]If it weren't for the fact that i'm loathe to rehabilitate my marantz gear i'd just as soon collect the parts for a 4-way melq setup over the next couple years and just listen to good music in the meantime. To reiterate; what i want to do righ...

The hypex are ready-made on boards that take no playing around without major complications. Sorry & thanks.(Btw, "tuning" is doable with ss -- but there's pain involved; by comparison, the versatility of tube is much higher)...

The 112's on my amplifier were made in 1926. I think they sound good but I actually chose them because I wanted low gain. Regardless of that there is a certain different pleasure to be gained from playing modern recordings using tubes made over 80 y...

The references to inertia and lightness are not to do with how a DHT works electrically but to do with how sounds reproduced by them 'can' be ie without smearing or overhang. Its a characteristic I hear in live unamplified music and one that is endea...
|
|
By 'lighter' I mean that the DHT amplifying stage subjectively has less inertia and is able to change direction more quickly. I suppose nimble might be a better word.
At the moment I usually do use the amplifier 'full range'. (My speakers will no...

What do you mean by 'sonic verdure'? Do you mean virtues?
If so I would say that they typically offer a lighter, unfettered presentation of timbre & dynamic range across the full frequency range provided that the HT and LT supplies allow them to....

I made a simple SE amplifier using the 6B4G for a friend. Initially, it was ac heated and sounded fluid & lively with a very agreeable gentle quality particularly with strings and woodwind. But, however I arranged the ac supply & hum bucking methods ...

Hi Romy,
I currently use a 3 stage transformer coupled amp with 112's, 71a's (as drivers) and your favourite 300B output valves:-) I'm not sure whether I'd go back to a capacitor coupled amp. I just acquired some Tango NC20 IT's to replace the NC...

What I'm speculating is that you might opt for cheap -- non SET -- amplification for now, and get acquainted with the application of tuning channels... experimenting how this can operate within your environment. I.e. put emphasis on the concept and u...

Surely all audio components would ideally be transparent not specifically the pre-amplifier. I have yet to hear any audio components that really are. (and I wouldn't be able to hear them if they were!)...

No-one is criticising the ML3 (amplification) product. We are discussing the concept and the applicability of such products, i.e. the ultimate limitation of an amplifier called upon to work from DC to daylight and, accordingly, drive a loud...

Romy says:[quote]The problem is that in context of those amplifiers the COST BECOMES THE MAJOR DESIGN IMPEDIMENT[/quote]Yes, but it shouldn't -- should it?Let's be reasonable (a tall order). Either a designer knows how to design or not. If he doesn;t...

Hi John,
I was involved with the Voyd originally. I have no connection with AN UK now except that I use one of their UK made Io cartridges.
With regard to the SP10 Mk2 I like it very much. It removes any sense that a record is playing. I use a ...

"One's mood changes far too much" Let's hope it's for the better, more positive. Happy new year!...

The visual analogy is very appealing I must say. Looking at audio from the point of view of music, as you treat the subject, I could comment on the following:"It is not necessary or even desirable that a system reproduce all the information of the li...

You know, extending the front baffle without making it take up too much space? Many people use the ubiquitous single driver on a narrow front baffle augmented by back-folded wings on piano hinges...I like those three mids; what are they doing -- canc...

As long as the motto "sell to survive" stands, performance parametres will kneel. If you want to sell -- and now we have a fantasmagoric global marketing opportunity, you start by being known.A magazine review is one way of doing that. A silly one is...

Here are some quotes from AA that I found interesting:
Rubber transmits vibration poorly, that's why it's used. Unfortunately this also means that it creates speed variation, mostly due to belt creep (NB I do NOT mean belt slip).
The motor is ...

As compared to the Melq, which is an amplifier. OK, it performs its job within a system... but, then, aren't other amplifiers "systemic" as well? I wonder whether other open designs are actually taken up by hobbyists... you do mention that ...
