That's a good move IMO,  while the Little Dot is a very nice amp and sounds nice, the synergy between the T90's and the Crack w/SB is so much better.  

Just plugged my T90's into the Bottlehead crack w/speedball and there is no distortion when cranked up so assuming it's the tubes or the little dot put out less power than the crack.   

I'm listening to that combo right now.   I normally don't listen at high volumes but when I turn it up now and with a few different sources(Pono, Rega Apollo CD) I'm not hearing anything other than some distortion being it's so loud, no static or noise between songs or quiet parts of a song. ...

@elvamir   +1, the Deckard/TH900 combo is sweet.

I used a Musical Fidelity M1 HPAP for a while before I got a EF6 and it worked just fine.  Depending on the incoming level I would sometimes have to have the volume turned all the way up but for the most part I always had plenty of volume.  It was also one sweet piece of gear - quality build...

Found used ones on Amazon that were 2 months old and like new for $999.   Also bought used HE-6's at the same time for $899 that were like new from another seller on Amazon also.    So would not hesitate to get more through there.

Hello,  I'm new here also and do not have the Edit Community Profile button​ showing for me in any of the browser that I try.  Can you check my account and see if you can fix it.  Thanks!

I use mine with the Audeze Deckard.  Sounds great!
