Quoting this just in case
There is plenty of good stuff going on here, just this thread is not the place to find it.
How do you know what I have done? Am I required to report on Diyaudio of every change and when I do it? I told the direction I am going but not every step of the way. Highest quality and accuracy is all Ii care about. How about you and your system? I do not find a lot of people here wiling to spend much even when they have it -- on their music systems. For many here, it is only an intellectual exercise.

you left out one word... omission.... 'rude'. all those who are as rude as waly and not willing to demonstrate change. .
There are not so many. He is in a league all his own.

Given you love to mention every new purchase even when its not audio I would have expected you to have done so.
I've already said on here I'm building phono stages at the moment. My system is oddly enough nearly all DIY rather than spendalot. This is after all a DIY forum rather than a 'fsck me look at how much money I've spent' forum 🙂
Who made first discrete solid state passive RIAA popular? Linn? W.Jung? N.Pass? Scott W? ??

We have been around a long time, Richard. Most here were not even in electronics when we first started to contribute seriously to audio design. The main factor is our success in making better audio quality.
Well of course depends what you mean by a contribution. Amplifiers most of us can't afford isn't really a contribution compared to some on here (and off).
You should use what you can afford. If you DIY, it is possible to make acceptable amps for under $50 if you so want. What is the problem with this? Do you need a schematic?
George thanks I didn't notice that it was Mark. Sorry about that Mark, explains why it didn't include any S. Wurcer circuit design!
I'd have to say that there are amplifiers on these forums the simplest chip amps to some fairly high sophistication and high powered designs. How can someone compare on price an audiophile consumer amplifier vs a diy design, it makes no sense to me to discuss dollar amounts, definitely not an apple to apple comparison. The reality seems to be that a talented designer or even just someone building someone else design in diy can produce an amplifier for substantially less money with no less of a quality build. I would posture that a good designer can exceed the quality level of most commercial products. I'd take whatever a few select people in this discussion could come up with, they would all be excellent even if different approaches are taken. There really isn't much economy of scale going on with the majority of audiophile products, those boutique audio companies aren't getting any type of volume pricing. So to say that a diy'er can't build something at a BlowTorch level seems absurd.
Then there was the friend who grew up in the Boston area where folks made fun of his name because his initials were B.R.A. So with his first offspring he wanted to be sure nothing similar happened. The name chosen was Byron Stedeford as he did not see any issue with B.S.A.
Didn't mention the chosen name to me before it was too late. Wasn't very happy when I pointed out the name was B.S. Adams. It had never even occurred to the pair of rents.
Now Bill take a chill pill. (Or smoke.)
RNM has quite a track record going back quite a ways, when he started dirt was considered "New Fangled."
His headphone amplifier is a well designed piece of DIY. As to boasting of whàt he has, that is a bit more of an across the pond issue. I perceive it more as these are my toys.
I recently learned replacement cost on one of my favorite gizmos is $185,000.00! I think it was worth fixing up the old one and keeping. After a bit of probing, the final cost of the well hidden repair part was $.035, but I did have to buy the minimum quantity of 100. Splurging on that turned it from useless back to almost new functionality. Cosmetics a bit less. (Point being price one paid for an object can vary considerably from other's perceived value.)
Now I have built some RNM and JC designs and they do perform much better than I would expect from the sum of the parts. Both by measurement and by my limited ability to perceive sound quality.
My most recent learning experience was in a stadium. The old loudspeakers were mounted below the catwalk in the sunscreen middle and had forward, down and rear firing units. My new ones were mounted on the outer edge of the sunscreen and fired to the back, covering from straight down to fully back.
What was not obvious until the comparison was what really happens. When you fire down, significant energy hits not just the seating but also the concrete floor which is raked up. This reflects energy at a right angle and across the field creating a destructive echo across the field. By pointing the speakers down a bit and back there is more absorption from the seats and the reflected energy is headed up. A noticable difference in an empty stadium. Less so when full of mobile absorption units, but still an interesting performance difference.
Now I consider that tale an interesting aside of modest value to most here, others have mentioned they consider it bragging. Personally I don't, as it is an admission of 40+ years of stupidly missing what should have been obvious, as long ago I learned to use low coverage angles in gymnasiums.
