Oh God... this misplaced poor tube largely exceeds my acceptance capability!

Performance though, set a new record with respect to how bad it is, taking over the slot for the worst measured amplifier to date.
Pipe organ?We need an option below "Poor".
I don't think they'd want channel SPL imbalance as well as larger distortion in one channel than the other.Thanks for the review Amir!

Isn't a lot of distortion what tube dude lovers nowadays want? Then Yaqin MC-84L can be an alternative. For the rest of us who want a clean and uncolored sound we avoid this amp like the plague.
But okay, it's just a hobby. People can do what they want.
I know you know this. I mention it to others.
As far back as the mid-1940s with the same power as the Yaqin MC-84L, there were tube amps that were better.
I am thinking of this:
Does anyone have a Williamson tube amplifier?
Or have had, listened to a Williamson tube amplifier? Impression? Are they available? What can one, in reasonable condition, cost? I could really imagine having one. Mostly for its HiFi history. :) Not as a main amp but in some nice secondary system. Then together with a subwoofer + LP/HP...audiosciencereview.com
If I interpret the technical data correctly, the old Williamson amplifier is better than a Yaqin MC-84L.
Yaqin MC-84L, which is from 2024! It's crazy.
I don't know man, the Williamson circuits were based on designs from the '30s and were way better than this. I honestly don't know why designers think that the use of valves is an excuse for terrible engineering.1930’s design level.
Maybe those with perfection fetishes should enjoy their music through such tube constructs every now and then, purely for therapeutic purposes

I don't know how tube lovers reason. A lot of distortion is apparently considered by these to be good, so maybe channel SPL imbalance is icing on the cake? Joking aside (if it's a joke?), what do these tube lovers want and how much of it? It's a bit of an upside down world. Why 1% distortion when you can have 5%,10% or even more? Or will there be too much of the "good thing" then?I don't think they'd want channel SPL imbalance as well as larger distortion in one channel than the other.
Of course! Unfiltered wide-band speakers in flimsy cabinets, or some esoteric 1st order crossover multiway with a vintage 1920s woofer and piezo tweeter thingy.Do tube lovers also want crappy speakers
Spot on. It is the Norman Rockwell painting of an integrated amp.There even may be people who like to reminisce to times when TV programs were without ads and telephones were meant for speaking to well-meaning and reasonable persons only.
I've got those (HFC) somewhere, if only I knew where... I remember Martin being very fond of conrad-johnson and Audio Research. The SINAD might've been mediocre, but quite a bit better than this one, and didn't they produce respectable power? I might even have considered giving them a try if the price wasn't so far out of my league.One channel does look like there's a suspect valve in there, bearing in mind the general symmetry of construction underneath?
If you look at some of the mid to late 80s 'Choice Amplifier books on the worldradiohistory site's UK page, you'll see many US made and very expensive amps with exalted high end status and with not much better performance Martin Colloms had by this time, gone over to the dark side, eulogising on the wonderful wide and deep soundstages with good 'pace and rhythm' yet diabolical measurements. Most of the good measuring stuff in these books lacked 'depth, aid and space' and simpl,y didn't 'flow' well. Look 'em up if you don't believe me
Oddly enough, I was thinking about guitar amps too.Hey, the ENGL (guitar) amp I measured had slightly worse stats..!
Tube harmonics are not the same type of distortion found on headphones or speakers.I don't know how tube lovers reason. A lot of distortion is apparently considered by these to be good, so maybe channel SPL imbalance is icing on the cake?

Do tube lovers also want crappy speakers, headphones that distort a lot?
For what might be worth, in 1999 I auditioned extensively a CJ integrated tube amp vs a Krell KAV-300i. The price was equivalent, the store was pushing for the CJ. Through my ears the Krell was superior on every count (besides being way more powerful). I bought the Krell and it served me well until I moved on to class D (Amirm’s fault ).I've got those (HFC) somewhere, if only I knew where...
