Jim, the “full power undistorted bandwidth” is the only bandwidth that counts, at least as I understand bandwidth. The 25Hz to 19kHz is it what would expect from a regular SET if do not spend a LOT of money for output transformer. Your amp is not SE ...

Ok, I did it a little different this time. At full power levels, the dB meter still showed wideband response. However, looking at the scope I could see distortion in the waveform. So instead, I lowered the input level to -3dB from f...

A local guy asked me that since my low-powe, full-range Milq is sitting in my storage and I do not use it then he would like to try it: he has 1110dB sensitive speakers and SET and PP amps. I figure out that if I give the Milqs to him now then I wil...

Many people in audio pursue for so called full-range. However, the proper reproduction below 50-60Hz and above 12-14kH is very complicated. There are huge amount of audio products and methods that can furnish the result in those “complicated” frequen...

Romy, I have not visited here since i made my splash on the forum back taalking about Dannoy. I wondered last week where things might be at for you and i chuckled to myself when I viewed your broadcast today.

The full-rage single-driver acoustic systems is probably the most hated playback topology by me. It is irrelevant if you use $200 Fostex or you use a family reserved edition of AER driver for $64.000. The result you have the same: a horrible dynamic ...

Antonis, the type of the hormone is your link it is exactly that type of the horn that I do not like. It has multiple bends, it means it has a fixed resonance chamber inside itself. My corner horns has none of it, it is just a mouse a radia...

I’m very much pro wider frequency response, as wide as possible. However, using juts a trim “wider frequency response” different people mean different thing perhaps…

Romy, is it a goal to make the horn strong enough to raise one end or turn it without having it fall apart from its own weight?From your earlier descriptions, I expected to see at least one continuous piece of plywood bridging the full length of the ...

To my understanding, taken individually, your attic horns would be more obviously working in a half-space environment. For any output that is common to both the L and R channels (some in the case of stereo recordings and all in the case of mono), the...

Romy, this is quite interesting; supposedly, the Marantz 10B was a knock-off of this, if I recall the lore correctly.Of course you will give this Grande Dame ('54 - '55 ?) a fair shot with some new parts, apropos? Especially new caps?I have out...

I need to admit that I am partially a full of shit in this subject. For sure all the audio methods that I have mention are very beneficial to play Bruckner but the essence of the Bruckner music does not come from some kind of proper playback methods....

Vinyl almost died after the launch of CDs, but today the popularity of vinyl playback is on the rise. Music stores are selling more music available on LPs, and many audiogon systems include turntables. So where are the full-function preamps? Before d...

Ultimately, as I have said in other threads, different people hear in different ways which will necessarily compel them to gravitate to different audio solutions.
We have to ask, when there are multiple paths to an audio solution, is the cost pr...

Well, I'm not so sure that the "friction from perlite or sand" inside the frame tubes is the answer. Yet, the way I picture "wall fastening", it is not to suspend the frame off the floor but it is simply friction or frictions critically applied to th...

Paul, I do not think that “before or after RIAA losses” requirement has any merit as no matter what kind type RIAA filter is being used it always will lose around 20dB. I do not think also that there is a “safest path” or “reasonably affordable”....
