Torq hope you see this before you leave. I am 70 have a slight ringing in one ear and have lost some of my hi frequency hearing, of course, because of age. I have been into high end equipment since the 70’s. I have been following your account of the Raal headphones. I have used a pair of Sennheiser hd 600 for years. What do you think the Raals for my main headphone? Also should I go with the Raal Amp? What Dac do you recommend. I was going to go the Headphone show this year in Irvine CA but they cancelled it twice. If you could help me for with a response I would appreciate it. Craig
