Really interesting comment as I have owned both for few months and somehow I do agree with you. I know you had a LD MKVI but didn't know you tried the Topping TP60.
When I just got the TP60 I was amazed how good it sounded with the HE-6 and for a while I actually preferred it to my LD MKVI, being a bit more transparent with slightly better bass and treble extension. But for the last few weeks I enjoyed my MKVI+ so much with the HE-6 I haven't used the TP60 at all.
I agree the differences are subtle but IMO there is still something very special about the LD + HE6 with the right tubes, especially the mids and voices, which sound so realistic.
Are you using the Soloist with the HE-6 and do you think it sounds that much better than the LD?
Despite enjoying my system very much I am still curious about the Burson and the EF6.
