just a word on my journey :
on both ends, i got a beepre and a fairly efficient unfiltered wideband speaker (DIY Davis MV ONE clone, 94db sensitivity), and I used to have a Coda S12 amp. Nice amp, balanced and running in class A for the first 20w, but a bit to analytical for me, even with the 'pre in front of it.
i realized a dream, bought and refurbished a 1962 Mc225 and.... almost magic !!
on the usability side, power is plenty enough for a 4x10m room, and the gain adjustment allows to fine tune the noise floor issues between the two tube elements, even with sensitive speakers.
i find the lower and mids to die for. best combination and musicality of the various setups ive tried in 25 years.
I still have a small issue with the top end of the range, some "ringing/sibilance" on high pitched female voices. I do feel it has something to do airborn microphonics, even if my bottles are equipped with herbies'rx. I'll try and put additional weight on them, using teflon coated brass brushings and see if it helps (couldn't find the vinyl covered lead rings in europe at a decent price)
but what a combination !!!
