Please Help me decide what to do

I had to sell my set up awhile back and am wanting to start to build a new one.

Previous set up:

Wadia 170i (only item I still have)
Lightspeed attenuator
Classe Ca-200
Paradigm sig 2's
Parasound Z dac

Signal cable silver res. cables throughout (still have these)

So I can't decide what to do. I can get a pair of sennheiser hd 700's for $450, and schitt lyr for $200, and a schitt bifrost for retail. I'm wondering if this set up will satisfy me for awhile or if I'll hate headphones compared to speakers. I've read reviews of hd700's being too bright...

If I do go this route, will the schitt lyr work well as a pre amp in my main rig later on once I build it? Will the bifrost satisfy me? I like the idea of using the lyr and bifrost together due to matching aesthetics, but sound quality for the $ is top priority.

I did like how simplistic my last set up was. 1 source, 1 power button, 1 knob for volume, no b.s., lean and mean and it sounded incredible.

I like all kinds of music and am super picky. Champagne taste, beer budget. I'm big on micro detail, resolution, imaging, tight controlled bass. I prefer a rich and warm sound over a cold dark sound.

Thanks ahead of time for everyone's help and responses!
