I’m lost. Help me find my way


I’m adding a headphone setup to my all McIntosh system. It’s shown in the virtual systems section. In short, it’s a HT system and the processor/preamp doesn’t have a headphone jack. 
My local dealer, who I have worked with since 1977, is recommending the McIntosh MHA200 amp and the Grado RS1x HP’s. I’m a Mac guy all the way since my first real system back in 70’s. I know nothing about Grado although everything I’ve seen gives them high marks. I respect and trust my dealer and will probably go with it unless I find the Grado phones uncomfortable or poor sounding after trying them. 
But I would welcome any first hand knowledge of either of these products. Thanks in advance.

Well I have found my way and I have made my decision. 
I visited my local McIntosh dealer a few days ago to order the McIntosh MHA200 headphone amplifier. As I have said throughout this thread, I’m a Mac loyalist and this was pretty much a foregone conclusion. (See my virtual system). He is also a Grado headphone dealer so I started by auditioning the RS1x headphones. I listened undisturbed for a little over an hour. No point in going further. I bought them on the spot. I found them to be just what I was looking for. And comfortable!  I wear eyeglasses and have always found headphones uncomfortable. Always. Not these!  
Anyway, the phones were in stock and I should have the amp in about a week or so. Thanks to all who responded. I appreciate your guidance. 

FWIW. No rule saying you can only have 1 headphone,

Others will argue but the Sennheiser 600 series is considered by many to be the gold standard for headphone tuning curve. Reasonable price helps,

I myself own 4 pair. Sennheiser and a HiFiman. Nothing exotic but good phones and fun to listen to.
