headphone DAC/amp

I need some advice on a DAC/amp for usb-driven Sennheiser HD650's.  I use this configuration when I'm working on my laptop.  I got a Shiit Vali 2 and Modi3 but am dissatisfied with the result - too mellowed-out, too laid-back.  This is a surprise to me because in my main system I really like the British sound (I have British amps and several pairs of British speakers).  Go figure.  So, I'm looking at a modest (sub-$500) DAC/amp that will do justice to the Sennheisers.  Here's what I've narrowed down on: a) Cambridge DAC Magic 200M, b) Shiit Asgard 3 with multi-bit DAC upgrade or c) E1DA 9038D DAC.  I know, these are very different solutions, especially the E1DA, but that's where I am.  Any thoughts or other suggestions?  Thanks.
