John C.,
A bit off-topic, but not really:
Have you ever considered an open-loop power amp with balls as an extension of the BT, but with easily available components. Not the exotic/hard to come by components.
- How would the topology look like (how many stages, etc)?
- Would it be something in the line of what Charles Hansen has done (see attachment) or does?
I've done quite some reading the last couple of days and from what I understand, the sonic benefits of open-loop (zero feedback) designs are best experienced when pre- and power-amp and possibly the digital source are all open-loop (zero feedback) designs.
It would be interesting to read your and maybe others their view on this.

I dont thinks that double blind test is in spirit of diyaudio
only for skeptical .here 119,053 member that messy with solder know ,we only need a good guide like John to go in right way

I don't understand your reasoning.
Of course anybody is free to fill in his hobby the way he wants. Most people, if they think hard for a few 100 milliseconds, realize that stereo is all about illusions and selective perception.
Knowing that your brain is easily fooled into thinking that an orchestra sits in the room while in reality it's only two speakers doesn't prevent you from enjoying stereo.
There are others who really want to know what the difference in sound is between two situations and who like to turn off as much of those illusions and selective perceptions, for example through blind tests. I don't see any conflict there; it's two ways to fill in your hobby.
Nobody in the blind test camp denies that it is possible to hear a difference between capacitor brands. We just want to make sure that the perceived difference is from the sound and nothing else. Surely that is a valid goal? If you're not interested in that, fine. What's the problem?
Jan Didden
dear Jan you are here in diy spirit ,that ok if work well for you and I know that can helps
but "double blind" was abused for the last 20 year I don't like see on the web the answer like "I cannot trust you if don't do double blind".....
Sorry my english is poor

No, your English is OK, no problem.
But the truth of the matter is that unless yo do a blind test, you don't know for sure if the differences you perceive are caused by the sound only, expectations, peer pressure, previous experiences, cost, size, shape, looks etc etc. or all of the above.
You may not like that, but you can't make a huge body of evidence and documented studies 'go away' by saying you don't like it.
But indeed, you don't need to care if you don't want to. Enjoy your hobby, enjoy diyaudio!

It regularly happens that I'm amazed about the variety of people's opinions on what's best in audio.
Just now 2 popular names came up in this thread: Dick Burwen and Scott brought up now Lynn Olson (the man behind the Ariel speaker).
The views are diametrally opposite to such a degree that I can't think of more different standpoints.
While that happens regularly here, I think it's especially interesting as both are certainly technically well educated and successfull.

I really like Nelson's saying that Audio is part of the entertainment-industry. While I respect both gentlemen, I enjoy this very relaxed.
Enjoy, Hannes

Lynn got the price wrong by an order of magnitude. Fill $350,000 into the blank and I have a hard time taking his comments seriously. Also I'm surprised, the valve amp bass boost is there and he is a speaker designer. Not accounting for it one way or the other when listening is just sloppy engineering. BTW I find Dick to be a little extreme in the other direction, but he knows his stuff and is very opinionated.
EDIT - or maybe the price when up/new generation? Does it really matter?

I'm not a recording engineer of course. Why should a recording need to sound loud and aggressive on CD? Marketing? I have some very good sounding CDs, like the now out of print Cat Stevens "Teaser and the Firecat" on Mobile Fidelity (Gain 2 System). The same recording in a reissued box set and a different label sounds bright and edgy. Anyway, it's unfortunate that the recording industry can't get it together.
Sony and Other music labels should phase out the CD and go to a an SACD or Blu-Ray audio format. I hope the CD continues its decline. Until then I'm buying LPs and SACDs whenever possible.

Yes. Google 'loudness wars'. Did you miss the protest by Metallica's fans last year?
Jan Didden
I know about the loudness wars. A lot popular material suffers that way.
Also, I also find that tone sweep test you mentioned very interesting. I hear sounds that aren't there all the time. 😀 Though, it's probably different mechanism and it's caused by past experience with a sound and conditioned reflexes.

Recording quality matters, no doubt.
However, the media matters as well.
Recently I ordered online a Gold CD of Gary Karr's Adagio D'Albinoni. Gary Karr plays Contrabass and Harmon Lewis plays Organ (Church Organ). It's a Japanese production and exceptionally good recording. I enjoyed very much listening to it.
Later on I found out that there is also a Vinyl Record of the same recording. So I ordered it as well. The CD, in itself, sounded very good. However, compared to the Vinyl, the CD sounds harsh and metallic.

As Jan says, the infamous loudness war. In short, stand out for any price when played in the radio and/or on cheap boom boxes and in the car.
Most of the music nowadays - especially in the US - is consumed in the car and has therefore to compensate the typical rather poor stock car audio.
Matters only to the buyers 😀
That amp is to 99.99% of all people anyway only of academic interest.
I don't know wether also other tube gear exhibits that bump, Lynn certainly does measure his speakers

frequency response and waterfall diagrams of the Ariel. As I see it, an interesting speaker.
Have fun, Hannes
EDIT:
As you worked as a recording engineer, you certainly now that vinyl has to be mastered differently, so the vinyl edition has to be different from CD (even though the recording may be the same).
Mono-bass, bass boost to higher frequency, high frequency roll-off, limited channel separation, single digit distortion playback with poor signal to noise ratio?
And still it's very nice 😀
That IMHO only shows that the ear is not that sensitive in the end.
Have fun, Hannes

One recording engineer told the story.
Once a band come to record their album. They demanded to record "AS IS, with no electronics modifications". He did, enjoying the result.
Late the guy run back with 2 CDs in hands: "Hey, this guys sound louder, listen! We want the same!"
