    Horns with SS amp instead of Tube (se)!?

    Hi Ralph, I have had some well executed Class A, no feedback PP Triode amps in the past (one was the highly regarded VAC 30/30 mkiii), which had zero to 6 dB negative feedback adjustment. I can confirm it always sounded better on zero, I can also say it was inferior to my SETs, except perhaps...

    I have had many big panels but the physics of crossovers, phase and group delay aren’t really different.

    Garbage in = Garbage out It’s a lot better IMO to get the best amps and sources you can and then find the perfect match with the speakers. Of course I used to be a speaker first guy like most audiophiles but I had some very clear experiences of sources and amps absolutely ruining the sound...

    Horns with SS amp instead of Tube (se)!?

    Nothing wonky about psychoacoustics. Only wonky is people who think they already know it all and aren’t open to there being a deeper level than “low distortion and flat frequency response “. JBL engineered the bass in their monitors in a more typical bass reflex design that benefits from some...

    A lot harder to integrate though. Btw. If you want good time alignment the woofer columns need to be in front of the main speakers not behind them. Stavros did this right in the Aries Cerat room last year wher he put the subs like 4 meters in front of the main speakers (long folded horns you...

    Nearly all the big pro woofers are doped paper and designed precisely to make big impact, so I don’t think paper is a problem.

    OTLs hate low impedance, into the lowest impedance on this speaker the output would be quite low and likely compress or outright clip. A SET with similar power on an appropriate tap would fare better as would PP tube or SS amp at around 50 watts.

    Oops, thought policeman Al is on the scene...better watch what I write now... Never mind the fact that the amp aspect came up very early on in the thread.

    You said distortions generically...what else did you mean? Surely you weren’t applying the Gedlee metric or even the weighting of harmonics like Shorter.

    Please direct me to the studies that show amount of distortion alone is correlated with listener preference. Geddes found no correlation between distortion (as defined by THD) and listeners level of unpleasantness in the SQ.

    Essentially the same thing expressed in different ways.

    Horns with SS amp instead of Tube (se)!?

    PP tubes can sound very nice if the amp is well executed, however, the will not achieve the same inner resolution and harmonic tightness of a good SET. No SS amp I have heard can achieve the same. The bass on the Universum might need some SS grunt but you won’t be doing the Be mid and tweeter...

    Disagree. Electronics first, electromechanical /mechanical systems second.

    Yes I was making conjecture...at least you got that (seems no one else did).

    Wilson Audio Chronosonic XVX First Impressions

    That’s my point, because there is no SET that could we will never hear the speaker at it’s full potential...it was a hypothetical situation...

    Wilson Audio Chronosonic XVX First Impressions

    That they can’t, so likely they cannot reach their full potential.

    So, they likely could sound even better if drivable by a top SET!

    Horns with SS amp instead of Tube (se)!?

    We tried Devialet on my Odeons and it was rather painfully obvious the flaws in three dimensional image and lack of bass weight (overdamped for this kind of design). I would look at the Reimyo KAP-777 as one of the few SS options that could work well on a horn.

    First trials of active horn speaker

    Interestingly, the noise level was acceptably low attached to my 110db horns...I was a bit fearful that they would be too noisy like my Mastersound (which is great on the SUprvoxes but was just too noisy for the horns).

    First trials of active horn speaker

    Update: Now have the WE91 derived monoblocks. These are LD+ MK2 91 monos that use a 274A rectifier, 310A input/driver and 300B output tube. This circuit was a modified WE91 design by Thorsten Loesch that gives a wider bandwidth. First trials are very promising...really nice sounding on my...

    Odeon Orfeo was another small speaker with a wooden horn.

    Something wicked this way comes... (2020 speaker teaser content)

    It was my understanding that a conical horn has the narrowest dispersion and thus would beam the most and be the most directional.

    The Sound of Analog, the Sound of Digital

    The biggest flaw in digital is likely jitter. It is inherent in the concept it seems and it’s audibility was never anticipated by the original architects of the technology.. Aliasing is inherent as well, which is why they quickly went to oversampling to push artifacts further outside the audio...

    The Sound of Analog, the Sound of Digital

    We are on opposite ends then because I think that most gear is poor sounding...even the really expensive stuff. By poor, I don't mean that it is unlistenable necessarily (although there is plenty of that, IMO) but that it does a poor job of approximating real, live music even if it ticks all...
