I swear that I already posted a response here this morning, but here goes again:
A couple of people asked how the JH|13 Pros sound out of the P-1u, so I thought I would post a quick comment. I already knew the P-1 drove them extremely well, but I tried the JH|13 out last night and the P-1u hit another home run. The JH|13s are so much better with really good amplification, and the P-1u / P-1 drive them better than anything else I can recall hearing. The silent background and very balanced volume control obviously factor into that performance. You forget you are wearing IEMs and the immersion in music is complete. Fantastic stuff.
blessingx came by last night and did some A/B listening with the P-1 and P-1u to see if they sound as similar as I feel they do. At first, he thought there might be some slight differences in presentation but after equalizing the volume level as much as possible his tentative thought was that it is hard to distinguish between them. Ric is taking the P-1u for a few days before it moves on to the next lucky member in the loaner program, and I hope he will post up his own comments and experiences with them.
I think the US P-1 was $2500 new and used ranges from $2100 down to stevieo's recent sale at or below $1800.
