Advise between Bryston B135 cube and Simaudio Moon 340iX

I have The Bryston B135 cube
with Focal Sopra 2s
Plenty of power great detail and soundstage
no harshness at all 
and 20 year warranty
Nordost Blue Heaven cables thru out 

I recently demo’d the 340i in my home system & was NOT impressed.It didn’t have that subtle golden glow that the old i5 amps had,sounding slightly cold & clinical on my Harbeth M30.1’s...There is a Creek "Evolution 50a with built in Ruby DAC board"listed for sale on usaudiomart.com for $1500.00 LESS than the Simaudio & IMO has a sweeter sound overall.Also the headphone circuit on the Simaudio was HORRIBLE,flat,colorless & lifeless,the Creek has a FANTASTIC headphone if that matters...Haven't heard the Bryston so no comment..
