??? What Is The MOST Expensive System You Ever Heard ??? What Was Your Opinion ???
Convergent Audio Technology is about 15 miles from me, and I get to hear the latest and greatest of the CAT amps and SL-1 occasionally... always very impressive. Usually in the $100K to $200K range, depending on the gear. I’ve heard the Magico S5 ... 
Tung-Sol 7581A......Wow!!
I like the VTA mods a lot.  They do have the Mk 3 and M125s in kit.  Not sure how different the Mk IV is.    
Tung-Sol 7581A......Wow!!
@artemus_5  Yeah, the blue is really nice...very photogenic! What I call "monoblocks" is essentially one channel of two separate Dyna/VTA 70s with SS rectifiers.  I think they'd be most similar to the Mk IV.    
Doozy of an amp question
I'd guess the Mac would be easier to resell if you ever wanted to swap it.  
HOW DID YOU END UP WITH YOUR DREAM SYSTEM?
Getting involved with the audio business got me off the typical merry-go-round of buying and swapping well reviewed mid-fi stuff that I was never particularly happy with. Working for Merlin and Paul Heath Audio gave me exposure to a much higher le... 
Tung-Sol 7581A......Wow!!
My technical tube knowledge is limited as well, but it looks like both have plate current of 54 amps with plate voltages of 350v. I’d guess the extra 5 watts is a fairly minor impact.   When I switched from KT66 to the 7581A, I didn't notice any ... 
Tung-Sol 7581A......Wow!!
AFAIK, the 7581A is an upgraded version of the 6L6 so should be a direct drop in.  
Tung-Sol 7581A......Wow!!
My Tung Sol 7581As have been in my Dyna/VTA monoblocks for going on 15 months now, with probably somewhere in the rough range of 500-700 hours on them.  Just wanted to reiterate how much I like these tubes in my system....there's been a little aud... 
I hate to say it, but now I think maybe I like my amp in ultralinear mode versus triode
Apologies if this came up earlier in the discussion...Do you guys re-bias and adjust for volume difference when you change between UL  and triode?  UL plays notably louder at the same volume setting than triode on my amps, and I'm assuming others ... 
Will one cable upgrade make a noticeable difference?
That's one of those questions that's impossible to predict, as the results will differ with every system.  If it makes any difference, I'd guess that it would be pretty subtle, so may take some time to notice.  The only way find out is to install ... 
I hate to say it, but now I think maybe I like my amp in ultralinear mode versus triode
Like anything, UL and triode will be a bit different with every amp and every system.  With my system with the Dynaco/VTA mods, triode is more refined with a more concise soundstage.  Especially notable with simple vocals, piano, and string, etc. ... 
Weak link
If room treatment of some sort is possible, I'd start there.   
Do speakers need to be re-broken in?
Speakers that have been sitting for several years might need to flex a little to get the suspension components working freely.  Some caps, depending on the type, might even need a little time with a voltage applied to get the juices flowing again ... 
Questions About Speakers
Every speaker and situation is unique so you really can’t draw absolute conclusions. Everything depends. 1. Speakers with foam surrounds will typically rot in 20-25 years and need to be refoamed or replaced, varying with climate....rubber surroun... 
Hagerman Trumpet MC review
Thanks for the review.  The Coronet is on my short list.  Hagerman is a class act, and a gifted designer. Even my modified Bugle 3 is on the impressive side.
