Bill, can you sum up the differences in presentation on TMayer 46's v TM 211's v Nat Magmas?
I’ll have a bash Marc. First up, please note that one needs appropriate speakers for 1.25 watt 46 amplifiers of course - I know this sounds obvious but you do see people putting the most inappropriate speaker / amp combinations together. So with that out the way.
Remember the AER Pnoe is ~118db and easy impedance thus you can make an awful lot of noise with milliwatts.
46 drives a 46 Monoblocks:
> The most outrageous, uncompromising authenticity of *tone* from any amplifier I ever heard. The net result is a level of frisson-inducing timbral fidelity that is SOTA
> Ultra levels of inner detailing throughout a very capacious stage.
> Extremely quiet amplifier resulting in that image “popping” holography
211 Monoblocks (standard 2 chassis)
> Potent drive and slam - a grip of iron
> Very high levels of resolution indeed (I don’t believe I heard a 211 this quiet and high in resolution)
> This is not a deliberately “pretty” sounding 211 amplifier - we are not talking about the cream silk addition atop strings for example)
> Lots of drive and foot tapping rhythm that makes you want to get an ASBO (antisocial behaviour order for our non-UK friends)
NAT Magma:
> At a macro level these are operating at a substantially lower level - why?
> The tone and resolution is markedly more coarse and of a lower fidelity
> Noise floor is a lot higher - not measured but would guess in the realm of 15db
> The presentation has loads of harmonic texture that appears as a colouration rather than what is on the LP imho. It is overblown I would say. There is plenty of bloom at certain pints of the mids if you like that kind of thing but honestly you’ll find it annoying on the back of a Mayer 211 listen for example
> Build quality is massively lower. Without wishing to be derisory, I would say the Mayer is like a Rolls Royce and the NAT more like a Fiat.
Anyway - with all this said. If you have very efficient horns that can be driven with a 1.25 watts and your diet is not solely electronica then the 46 is the weapon of choice. If you need more juice, you should take the Mayer 211 (I haven’t talked about the differential Mayer 211 in order to keep the comparison fair with the 46). The NAT is rather funny to look at and some might need 170 SET watts - personally I find that level of SET watts with that tube a bit silly although quite amusing. I don’t find the sound compelling at all.
