Pdreher: No. But replacing the tubes is a much more complicated procedure than with most other tube amps. One of the after market tube suppliers (I believe it is Triode) has a video of the procedure posted. 
The closest approach: what amplification?
Pubul57: It's hard to disagree with FVA that we are being marketed to death. I know people in trade need product to sell, but the better approach is usually the evolutionary one you suggest. I am happy to buy affordable new equipment in order to g...

Atmasphere: I must be getting tired because I misread your opening paragraph.Please ignore my response.cheers

"IOW understand the rules of human hearing" is surely an overstatement. Hearing evolved along with the brain, and our survival and social needs for eons. We are a very long way from a complete understanding how it interprets information.

Back to amplifiers: There is general agreement about analog amplifiers. Solid state has the least distortion; the output resembles the input better than tubes. Are the tube folks all crazy? Do they like the sound of distortion? No they are not, bu...

" I do believe there is a reality out there that is objective, which defines the real thing"Ah, to wax philosophic! Well yes and no, perhaps, we'll see. Sound waves are "real" in the material sense, but hearing is not. My teenager will be exposed ...

"We listen to a system not a amplifier"Yes and we listen to different recordings, so how can we determine anything beyond that we liked a specific song, on a specific system, on a specific occasion?I maintain that with experience and consultation ...

Unsound, I agree that it is developing slower than it could. My amp's basic design is ten years old. I have done no marketing research, but I suspect that since all the money is in home theater, the larger HT companies are waiting until that marke...

Tricks: Digital amplification is inherently capable of performing complex processing without causing additional (unintended) distortion. I can compensate for room acoustics, draw and save my own response curves, program various real time correctio...

When I go to the symphony I am acutely aware that where I sit in the hall dramatically affects the experience. Under the balcony the bass is emphasized. Seats far away homogenize the sound. Up close the orchestra really does "image" with the violi...

To try and answer your rephrased question, triode tube amplification has most often yielded the best result for me across a wide range of speakers, however, since it has also been a giant pain at the practical level, I have looked for alternatives...

P.S. As I recall, some interviewer once asked Peter Walker how far he had pushed audio reproduction towards the goal of perfectly accurate reproduction. He said; about 15 per cent! (I have not looked this up so be kind, it's Christmas) 
The closest approach: what amplification?
Any reproduction can only be selections from the original, plus the additions and distortions. I can tolerate loss of information and distortions better than the additions! So low hum and noise go to the top of my list. The distortions and editori... 
Why so negative about McIntosh speakers?
For many years McIntosh dealers sold Bozak speakers as the complement to their electronics line. Then McIntosh tried to market its own brand of speakers. This happened about the same time that Marantz, and other competition began to reduce the mar... 
Tubes for Modulus 3A
Have you tried using the tubes from your 3? What result?
