I have MC60s and a reissue C22 the CE from the mid 90s. I find it to be an excellent combination . The speakers i'm unfamiliar with. I find them pretty forgiving though unless you completely miss match them.
I recently bought a pair of MC30 that were restored by Vintage Vacuum Audio. Yves did really great job, and they sound fantastic. MC30 and MC60 are the only two power amps that were made by McIntosh using tube rectification, which gave them a more vivid tube tone compare to other McIntosh tube amps. I had a pair of modern MC75, sold them right after I got my MC30, never regarded that decision.
for either the MC30 or the MC60 get a set of PSVANE 5u4G HIFI grade coke bottles and be prepared to hear the sound stage open up....
Hello every one, I would like to know, if any one, has had experience with Allison 1s or Allison 2s. I, Have a pair of Mc60s with a Mcintosh C22. Would love to hear your thoughts.Thanks
That's just silly. I've been satisfied for decades ...You will never be satisfied .
It's the nature of the hobby.
I never had belles but on paper the those 2 pres should be excellent with 60s.

I started with an MX110 and MC240 in 1990 - my father bought them for me at city wide rummage sale for $70 along with some JBL Olympus speakers if you can believe that. Since then, it's been one heck of a journey but at no point did I ever feel that I needed some other piece of gear to enjoy music more. From time to time, upgrades have been made sure but in most cases to serve a new goal - upgrading from the C100 to C200 to add the HT PASSTHRU feature for example.Yet you keep buying new toys and trying new things
I guess a truer truth , you can get there but you still feel inclined to find another way there.
Personally, I owned three pair of MC60s - only Mc gear I regret selling.Still... the pair of 30's are on my mind when i havent even taken my 60's for a stroll yet! Wanted to replace them paper caps and bublebees first. Already did the diode deal, got some Russian 4y something or others... these Belle just look at me yearning....

Shat..couldnt help myself. Bought the 30's. Looks like the OP and i will have a common theme. Maybe the 30's will be fine on the Belle, and i can move the 60's to the Super Heresy HIP's... rabbit hole here i come.Personally, I owned three pair of MC60s - only Mc gear I regret selling.
HT passthrough feature. My c-2200 has that. Been wondering what to do with the feature.i like your logic.I started with an MX110 and MC240 in 1990 - my father bought them for me at city wide rummage sale for $70 along with some JBL Olympus speakers if you can believe that.

Never owned 30s
I restored a pair of 40s for someone so they were both in my system (40s and 60s) Not a tremendous difference IIRC.
I've heard 225 in other places on other speakers so it apples to oranges. So far 60s are my favorite. I'm interested to see what you think.
The Mac classic tube amps are fixed bias, set with soldered-in resistors. When restoring a unit you can adjust the bias by changing the values of these 2 resistors, but they need to be closely matched so each output tube gets the same. Over time these carbon comp resistors will have drifted in value. I am unsure why Mac went this way, other tha perhaps the unique output transformer design made it possible to not need individual adjustable tube bias. Macs first integrated tube amp, which had a solid state front end, and tube amp did have bias pots on the chassis, but then again the output transformers were not the bifilar/trifilar design of other Mac amps.Excuse please if not a good spot to slide this question in, please let me know otherwise.
I realize mc 30/60 are fixed bias. Is this to say that the tubes have no bias measurements to be had? Most amps ive owned were adjustable, and also autobias. I know little, but how to use a meter and screwdriver. Am i grasping to assume the Macs would have a bias that can can be figured somehow, but its just not adjustable?
Heres why i ask. I thought to use a set of Tung sol kt66 which are said to pull 900ma. Safe for the mc30...good bad right or wrong as far as sound, just wondering if i can monitor things with one of these contraptions:

If i get a reading from my current 6l6gc, can i compare that to readings of thosnother set of tubes to determine if its within limits of the amps?
The amps in question are feshly restored from Vintage Vaccuume Tube Audio. Why do this? Just wanting to eek out a bit more upper frequencies if i can do it safely.
What im getting at is that given that its fixed, whats it fixed AT? Doesnt the use of these bias resisters of varying value depending on a voltage measured at specific location indicate that its therby "set" so a specific value, and if so whats the value,AND can this value be measured with the device ive LINKED to?The Mac classic tube amps are fixed bias, set with soldered-in resistors.
