The first thing to address is what tube sound are you referring to? The really is no such thing that is a standard. A Dyna ST70 sounds entirely different from a Dyna ST35 that sounds different form a classic Fisher that sounds different from a classic Scott and all of the sound entirely different from a tube Marantz, McIntosh, or modern tube amps such as those from ARC, Cary, etc. My classic ARC D76a amps had not similarity to any of the vintage tune amps I've owned nor any SS equipment I've had. However they were easy to identify in listening as tube amps.
If discussing generic vintage tube amp sound as perceived by many, then probably the closest would be the 1st and 2nd gen McIntosh as Frank was careful in voicing these amps to come as close as possible to Mc tube amps. Other companies tried but were less successful and others did not try to voice thinking the ss sound must be more realistic than a ss amp voiced (talk about a disaster).
As a group, I have found the early Sony receivers seem to have similar favorable attributes for me. I tend to have a low threshold for listener fatigue and my ear training was with vintage tubes and 1st gen McIntosh SS. The Sony 6060FW is really the only receiver I've heard that I can play for hours without a problem. Even later Sonys will fatigue me after some time but not as fast as others. The Mc 1700 (actualy a hybrid) and the 1900 also do well in this way.
Some companies have a darker liquidy sound such as Sansui and Marantz and some think it is tubelike but it is more of a smearing of detail and what appears to be a slight frequancy bias in the lower range rather than actually voicing. Either of these brands are okay but, I'd suggest the Sonys such as the STR 60x5 as a strting place for the vintage generic sound if that is what you are referring to.
