Is there a Solid State amp that can satisfy a SET guy?

Neither can Class-D because of it's switching frequency and associated output filter to get rid of it, that brings phase shift down into the audio band as this shows in red. https://ibb.co/sjNy1Fq

This statement is false in that it ignores entirely self-oscillating amplifiers which are able to correct for phase shift. All the class D amps designed by Bruno Putzeys can do this. Self oscillating amps have been around for over 15 years.

However, it still does not grab my subjective and emotional senses. Could SS be a more objective and intellectual exercise?

You are touching correctly on something about how audio interacts with the brain. The brain has tipping points- in the case of music, its normally processed in the limbic centers. If the brain picks up on something wrong, it will move the processing to the cerebral cortex! Suddenly the music is less involving. IMO/IME, if you want the emotional involvement (and since music is an art form as old as humans themselves, emotional involvement would seem pretty important) then at least for the time being, you're going to have to deal with tubes.

@lewinskih01 The difference between the XA25 and SIT-3 is very hard to put into words but in a nutshell the XA25 has more bass control and weight the overall presentation has a little more authority will a little more defined presentation of the soundstage and instruments. With the SIT-3 there is a sense of tube bloom, both amps have this but it`s more noticeable with the SIT-3. For me it was a give and take what i had always wished a SET could be better at the XA25 brings. Does the XA or SIT-3 sound like a SET amp? With 3D imaging yes but the tube bloom of lets say a 300B tube is not going to be there but you will have traces of that signature and the XA25 and SIT-3 maintain the realism that SET`s are famous for.

Pre-amps have a big impact on how the SIT-3 and XA25 present their sound currently i`m using a LTA as a pre and the combination works really well, i just placed an order with Supratek for a Chardonnay pre, i had heard one of these pre`s about ten years ago and i have never forgotten how great that pre sounded and now they have a gen3 that`s even better from what i have read.

What i listen too is all over the place, classic rock is at the top, then jazz, jam music, progressive rock Porcupine Tree for example then the classics Frank Sinatra ect. and others Sade, Nora Jones and so on.

Hope this helps somewhat.

You are digging your self a big hole Ralph.

@rh67. I look forward to the compare and contrast of the LTA and Supratek with the XA25 once you have it all settled. 

@annika I`m excited to get the Supratek and pair it with the XA25.
