Tubes vs Solid State - Imaging, Soundstaging, 3D

Well said, Jeff (Jwm). I would add that besides the reaction of your friend being immature, it also reflects a lack of understanding of the fact that the sonic performance of the specific digital cable in the system in which he heard it may have been completely different than its performance in your system, due to differing interactions between its own technical characteristics and the technical characteristics of the components it was connecting. Even for a given cable type and a given system, differences in the length of a digital cable can result in completely different sonic effects, for reasons that are easily explainable. Those interested can read this paper by A'gon member Audioengr (Steve Nugent of Empirical Audio).

Undoubtedly in many arguments about the sonic performance of audio components and cables those on both sides of the argument are correct, in the sense that they are accurately reporting what they heard. But what is often lacking on both sides is an understanding of the interactions and system dependencies that are involved. Interactions between amplifier output impedance and speaker impedance vs. frequency characteristics, for example, amplifier output impedance of course being very different between most tube amps and most solid state amps.

To me, differences of opinions are respected... and expected. I do accept some agreement and even common sense and experienced knowledge.
But lets keep it interesting :)

Metralla...I was being ironic...or sarcastic...or something...Since when did people start taking this stuff so literally? Is this an Aussie thing? Also, it is difficult for me to get by the fact that Isochronism has a Sunn 2000s, and that it's only 120 watts...I thought the 200s was 100 watts, and the 2000s was much more...now I have to look this up. I looked it up, and yeah 120 to 150 watts...200s only 60 watts! With the 2X15 cab (a classic and the best in its day) it seemed like more juice due to efficiency I suppose. Off topic, but I can't help it.

I know, and my comment was in the same spirit. I was amused by Melbguy1's cricket reference.

Carry on.

Wolf, When I finally found a correct original matching cabinet, the version with the single Cerwin Vega 18', and you are correct in that the other option was a dual 15" JBL D140F cab, the speaker was blown!!
The 18" is 4 ohm and 2-15" is 8 ohm. The amp has an output tap for each.
The full stack would have one of each cabinet!!
