The other thing to consider is having a DAC that has a balanced output. The iFi DAC I have doesn't have any balanced output. I've heard it with a balanced amp and the differences back and forth are negligible. That's what makes the iCan Pro tough to justify. If iFi does release a DSD Pro DAC it's rumored to be in that $2k range.:eek:
Not many Grado folks here do their higher end HPs with some sort of balanced connection. Personally, I would only have balanced cables installed to the HPs I think would benefit the most. The GH1 would be off limits for limited edition reasons.
I'll throw my hat in the ring, I had the GS2ke preordered with the balanced cable option. The turnaround for it was a few days later than standard cable version. My brother is just as interested in it as I am, so I'm looking forward to listening to it on his setup as well. I also have a Pono player for which I need an adapter but it'll be another way to get a balanced signal.
