How to tell vacuum tube is gone bad??
Hard to tell with this scenario. You will need a tube tester and test the tube for emissions and a life test to verify the tube operating within spec. I'm not familiar with the amplifier but if you move the tube to the opposite channel and perform... 
Upscale RCA Jacks - McIntosh
I agree, I don't think the "better" jacks will sound any better or worse, The better jacks are secure to the equipment panel and will not break away from tight or heavy interconnects. I have damaged a few cheap rca jacks with tight rca male interc... 
How did "Oh Mercy" end up sounding so great?
Im not familiar with the recording, is the album a DDD recording or analog part of the recording process? 
Teledyne Acoustic Research Ar9 speakers
AR9 need power to bring out their potential, 200-300 watts/ch. nice sound but somewhat off in soundstage accuracy.Dunlavy's are very accurate speakers, bass never seemed to be a problem for me. The Dunlavy's are very room and placement sensitive. ... 
Tannoy Black Value
Why do you keep posting this question? Your question was answered more than once. 
blown amp - vintage speaker the culprit?
Highly unlikely the speaker caused the problem unless the crossover/caps were out of spec to the point the impedance of the speaker dropped to 1 ohm or less, essentially shorting out the channel in question.This looks like a boutique or DIY type s... 
Tannoy 15" Blacks
With crossovers in excellent condition 15K a few years ago, less now considering the economy 
McIntosh MC-2300 amplifier or... ?
1000.00 is a good price if the amp is in an 8 condition. Ask when it was last serviced and who did the work. All the big Mc amps from that era are in need of a re-cap/service work 
MacBook Pro output to DAC
I use the optical output as explained above with better results than USB. I believe you also have a firewire connection? but you would need an interface to make the connection if your DAC does not have a firewire port. Firewire is best used as a d... 
Problem with bi amping speakers
Thanks Al I got it now. I had to look at the picture again of the Dussun 
Problem with bi amping speakers
Al Let me ask you this, if the jumpers are removed this disconnects the integrateds amplifier power output so hence the need for the "Y" cable Ed 
Problem with bi amping speakers
AlI seem to think with this type of connection Manitunc has made introduces the impedance of the tube amps input stage into Dussun loop through the Dussun preamp section. This would seem to be the source of the overload to the Dussun preamp stage.... 
Problem with bi amping speakers
I went to the Dussun website to see the amp you have. I'm not sure I understand the "Y" phono connections you are using? The website had very good photos of the rear of your Dussun so I will ask you a few ?I did see an "line out" on the back next ... 
Problem with bi amping speakers
The more I read your post It seems like you may be getting a feedback from having your tube amp connected to your integrated amp. How close is the tube amp to the integrated on your audio rack? 
Problem with bi amping speakers
Do your speakers instruction manual talk about bi-amp configurations? Not all speakers with dual binding posts and jumpers can be bi-amped only bi-wired. Don't try to bi-amp until you get more info from PSB.
