Enter the Altec 9440A which I just recently have the pleasure to experience. Untimely as it appears, it seems appropriate at this later stage to conclude the only advances available in audio sq imo/e is transparency. Good luck out-doing the Altec. Coloration is either incidental or by authorship or both by default. Transparency otoh by planned result is rather elusive. Those that have attained the closest approximations have been the most acclaimed. Realistic reproduction has always been the most desirable by the majority. Leaps since the hey days? I think not. Updated circuitry? Sure, but better sq.? Sure...a little. Guaranteed the exact same sq of current product could be achieved using components from the 80's.Oh well, another post pretty much ignored.
I prefer amps that don't sound like anything.![]()
Despite the Stereophile null test of a carefully tweaked Carver amplifier the production T Series (for transfer function) models never achieved the same amount of null versus the target amplifier. Yes all Carver amps have their own sound. Is it the same as the Conrad Johnson target amplifier? NFW except for the one BC personally tweaked..Enter the Altec 9440A which I just recently have the pleasure to experience.

Not relevant. There are good PA amps that are transparent just as there are home amps that are not..The Altec is a PA amp.

Google loves me.Maybe I need to spend more time at the Guitar Center![]()
Right, but that was (clearly?) not my point. It is in reference to the op and your post #25, 27.
Referring to Bob's ability
I believe you. The point I'm making is leaps and/or bounds have not been achieved since then in sq. as has been suggested. Natural, progressive, incremental increases as usual are all that have happened.I have no problem with BC's ability. However, the production T series amplifiers never achieved the same null as his tweaked test amplifier.

Restored Bose 1801's are considered to be very good sounding power amplifiers regardless of age. All the Mac fans will pile on concerning the MC2205.
You can do better. The Macs are second to none in build quality. Nothing special otherwise imo. Can't speak to the Bose but I would throw your notion of synergy regarding these amps and the Kefs straight out the window. If the Bose sounds better, it's a better amp, period. The 2205 is plenty adequate to demonstrate the Kefs.I do agree that preamps can add more color to the sound output of an amp, but I'm a firm believer that the synergy between the amp and the speakers are more critical.
I did do an a/b test between three preamps using the same amp and speakers. The preamps were C32, C26, and Bose 4401. The amp was my Bose 1801, and the speakers were Kef 105s. I couldn't hear the difference at that time, but I have heard the difference with lower end pres, but that is not the intent of my thread.
The intent of this thread is me wondering if a new amp costing around $6000 would sound better than a high end amp from the 70s. But perhaps the confusion is my own in that I think an MC-2205 or a Bose 1801 amp are high end vintage amps?
If that is the case, please forgive my ignorance. The 1801 is the best sounding amp I have heard.
I'd like to think soI'm thinking you could get some really good modern amplification for $6k.
