Why don’t you borrow of purchase a high quality Class A SS amp and do an AB comparison with your tube amp. You should notice that the SS will sound more accurate which might lead you to believe it’s more transparent but take notice to which design engages you more and which draws you into the the music better. See which gives you a more 3D dimensional soundstage and which design throws the soundstage out further in the room, not just behind the speakers but out towards you and even behind your listening position.
This is exactly the kind of wise, experienced, helpful comment that keeps this forum vital and worth reading. Thank you, lowtubes!
