Pdn,
I use two in my home office system; an Eastern Electric Minimax (w/ Telefunken NOS) and a Raysonic. Though the Raysonic is, IMO, a much better all around machine, the Minimax with the Telefukun tubes is a detail monster.
To my ears, the Raysonic has a much more physically wider presentation of music and seems more balanced tonally vis a vis the Minimax. Thus, for most 2-channel music I stick the Raysonic. However for certain particular CDs where solo music, accoustic guitar, is emphasised etc., the Minimax is called up for duty.
In line with the above, due to the narrower soundstaging, the Minimax gets nearly all the word for listening via cans as, by definition, the soundstage is naturally limited.
Cheers,
