Why Can't Modern Tube Manufacturers Make a Proper Tube?

@pindac

I must disagree that tubes have had their day in high end audio. Certainly from an overall perspective… consumer goods… etc. But in high end audio a number of companies attempted adoption and backed off because they could not reproduce with solid state designs the realism and musicality. Audio Research for instance, tried to us solid state and ultimately gave up. It is more like the advent of CDs and the renaissance of vinyl. I believe the vinyl renaissance is coming to an end, but not the tube.

At some point solid state will surpass tubes in the high end. But it is likely to be two or three decades away. I am living in the moment and want the best sound possible today… for me tubes provide that. It is also true for an awe full lot of folks with deep experience in high end audio.

Uh, they can and they do. I've had no issues with many KT150's I've bought for my ARC amps, same with Electroharmonix and others- in fact, I've had no issues with any tubes I've bought.

We all like tubes and they do a better job than solid state.

 does anyone here have an understanding of what atube does within in an amplifier? Why are so many used in the more powerful amplifiers.

So the current flows through A vacuum tube versus a solid state circuit. ok, that's good info. What is being achieved with all these tubes? Current flows in and causes a filament to glow and then current flows out. So what's being accomplished?

In my case, I'm not talking about "issues" I'm talking about how I never tried NOS until very recently. I've never had and issues w/ Gold Lion, but the sound difference was remarkable when I used some RCA pre tubes and some Mullard input tubes. I am still running Gold Lion Power tubes and really dont see myself changing. Four KT77's cost me under $400 and will last me 2-3 years. I dont see myself spending 3 times that amount for the same time. Thats just me.

But, its not about issues, its about much better sound.

My question in the beginning was, why the difference in sound quality and I think we've had some fine explanations from the gallery.

Silly.....that's where the leprechauns frolic.....in the tubes.
