Don't know about all your comments there, but extolling YUIN pk 1 is exactly the right thing to do. Had them 9 or 10 years and they continue to surprise. Simply awesome.

Yes, indeed, with the YUIN PK1, it's that incredible, awe-inspiring sound stage that keeps things fresh and enjoyable for me after so many years of ownership. They are just marvelous. 

I thought I was buying a player,(X-1) in which I could install an SD card filled with music files from iTUNES, or Amazon libraries, attach my new Sennheiser Momentums and amplify with my new Cayin 5 and.......nothing. What went wrong?  That's 3 new products. Was the Fiio X-1 purchase my fatal...

No, Andrew I think you might be misunderstanding what I posted about YUIN / HiFi Man customer service. They were great. I was wearing the ear buds when I was using scissors and sliced right through the delicate cable they have. No, they promptly sent new  ones even though warrenty was defunct...

I use PK1's with a PORTA CORDA 3 MEIER amp. The PK1 is just so detailed, so clear, with an amazing soundstage, that from the start I had the rare feeling (for me) of not even being curious about any other in-ear headphones. I'm speaking from a quite limited, narrow experience with ear buds...

Yes, RASMUSHORN, I did try the G-CUSH's on my new 325is cans and I do agree. These huge oversized pads do dilute the signature GRADO forwardness to the sound's disadvantage. I aso thought they looked disproportionate on the GRADO's compact little body as they hang from the banana hook...

2 months after warranty expiration I sliced my PK1 cable in two. I wrote them, explaining situation, and asked them for repairs for which I would pay. I ended up with a new pair. They could not have been more accomodating or anymore kind than they were. Great product. Great service.  ...

I got the C model from AMAZON, $11.50, after seeing pictures here. Got another one too, called a scroll, which is the motif of the base. This one is black. It's shorter, just as sturdy and functions just as well. Both are quite elegant. The company is SPECTRUM.

I wasn't going to let my new 325is shiny chrome headphone lie around on its side, lorded over by my AKG 701 on its little plastic throne. So I took a chance on the " banana holders ". I ordered two. Thanks to those on this thread who presented me with the idea, supplying your opinions and...

It's a genuine opportunity to hear such detailed and thorough consideration from someone so dedicated to headphone conoisurship, and someone fortunate enough to have access to so very many phones. Headphone pornography. I need a bib for the drool. Would love you to let go candidly with general...

Thank you for the welcome RASMUSHORN,   So you're telling me I spent $ 45.00 for G-pads just to destroy the good sound of my brand new 325is's ? Well that's bad news. We'll have to see. I'll do comparisons as I go along. I was just trying to get set-up properly  from the beginning with...

Reporting for duty- Received my new 325iS yesterday. S/N 6619. After 2 years listening to main house phones AKG 701 and GRADO SR 80 decided to move up GRADO chain as high as I could go. That was my goal since hearing cable-modded GRADO RS 2 a couple years back, after meeting a stranger...
