Brumeister 099 Pre+DAC

Upon the dealer's suggestion, I plan to buy a new Brumeister 099 Pre+DAC which I haven't listened b4.  
Since there is few discussion on this brand and it's gears.  I would expect those who familiar with this brand or this model can provide their opinion for this model.  My current pre is Accupase C275v+ A47 and speaker is Harbeth 
super HL 5 40th.  

Thank you in advance.
