Dac/Amp to drive Sennheiser HD6XX and Shure SRH1540 ??

[ld100]

Looking for Dac/Amp to drive Sennheiser HD6XX and Shure SRH1540... I tried Fulla 2 from Schiit and did not like the sound... In my opinion poor highs and lows. Sounded thin and unnatural... I prefered my Dragonfly and returned Fulla 2. I need a desktop unit (or units) that would fit on a desk. Do not have to be tiny... And need be a higher build quality. Under 500-600 preferably. I am very interested in Grace Massdrop unit, but it seems that it is not a great match with HD6** series. 
 
Any others? Desktop only. Not portables... Thanks

AudioGD NFB-11

Modi Multibit and Vali 2. Probably the best pairing under $500 for the hd650/6xx. Will power just about anything else you might buy in the future as well (except maybe the HE-6).

Audio-GD makes some good stuff if your looking for an all-in-one unit.

I can vouch for Audio-GD. I have the NFB-28, and it surpassed my expectations. My HD6XX and LCD-2.2F sound unbelievable on it.

If the 11 is even close to the 28, it will suite your needs wonderfully.

I would think the DragonFly on it's own is fine for driving the 46-Ohm SRH1540.
Get the Darkvoice 336SE ($214-$250) for driving the 300-Ohm HD6XX.
