Atma-Sphere M60 Mk11.3 vs Audio Valve Baldur 70 W

What type of loudspeakers do you like?

The AtmaSphee web site has some preferred speakers listed that pair well with their amps.
Thomas is right. AtmaSphere amps have a certain purity that I have not encountered in other amps.

Thomas,
If the Atma Sphere is a OTL, then would the Audio Valve be a SET amp ?.

Could you describe the difference between the two, I see that you own the Atma-Sphere. Maybe you can describ it for me.

I have heard the Baldur, the only valve amp I have audition so far.

To me it seemed to have good Bass, amazing detailed midrange, actually ,I had never heared anything like it, being SS. I seemed like it had very good PRAT.

appreciate your comments

i havent heard thh audio valve..

but the atma-sphere with the right speakers is "totally one of the most rightous" sounding amps bar non ( they also will do bass !!!!)

hope that helps,

Mike

Tube amps have their voltage stepped down at the output of the amp through an output transformer. The best of the best tube amps have very expensive custom output transformers to minimize any losses. The output transformer on many designs is the bottleneck in the system. If done properly, these designs can be quite wonderful.
An OTL or "Output TransformerLess" amp does not use such a device and steps down the voltage through a series of output tubes. The advantage is this avoids any possible coloration caused by a transformer. Possible disadvantages are speaker matching (they like constant loads) and heat (they run in Class A).
OTL's are unmatched with the exception of very few transformer coupled amps (which cost $$$$$).
