I could not agree more with sheldon. The HA-1 headphone amp is going to be something and is way up there near the top of the class of reference headphone amps, I would gainsay. It remains a spiritual revelation every time I put in well-recorded CDs. The tone and timbre of instruments is achingly sublime on acoustic and jazz pieces.
Rob and Kurt were very gracious. The customer service at Echo is beyond excellent. I shall return...and I sincerely hope to be at the next Portland area meet. There were several pieces of fine gear I did not have a chance to listen to as I had to leave just as the meet started to rock...the Fosgate and Yamamoto looked very cool and I look forward to impressions from other attendees about those two tube beauties..
Echo is a great place, no doubt. Kudos to Rob for a wonderful time...
