The SMIV and Reference were the first headphone amplifiers I had ever purchased and used. I paired these two amps with some brand new Yuin PK1s when I received the amps back in March. At first, I was very reluctant with my purchase and thought that headphone amps didn't make much of a...

I picked up the PK1s back in April or so when my Xin SMIV arrived. When I first got them I thought they were awful (I complained somewhere on these forums too). Granted, I plugged them into my new SMIV and listened without letting either burn in. The sound was very distorted to my ears. It's...

I'm really considering dropping $45 on the KSC35's now that they're back in stock at Koss.com. Are they really worth $45 though? I know they used to be much cheaper...

I received PK1's today from HeadRoom and so far my impressions are similar to yours. I've allowed them to burn in for most of the day and now they are going to burn in through the night. Hopefully that's all these need.

I got back from vacation yesterday and found 2 amplifiers in the mail. I thought battery installation in the reference was kind of tricky. It seemed as though you needed to push 4 batteries in at once to avoid moving the large cap. On top of this, the foamy material keeping the cap in place...

Ordered SuperMicro IV- March 7th, 2007. Received invoice & shipping notice - March 18th, 2008. At some point, I expressed interest in a Reference and I did receive responses from Xin. I decided to stick with the SuperMicro and did NOT order a reference. I also changed my address 3 times and...

guffaw In all seriousness, I'm glad to see he's responding to someone. I'm sure mine is close to production!

I hope it works.

I e-mailed Xin and offered to buy a reference in addition to the Supermicro IV I ordered 7+ months ago if he shipped the amps soon. Unsurprisingly, I haven't received a response. I'm starting to think that he isn't motivated by money...

I'm so excited. Today is my 5 month anniversary.

March 8th seems so long ago. Anyone know what he's doing now?

Thanks for all the input. There's clearly too many choices. Does anyone else have anything to say about the Yuin PK1? For some reason I'm liking the idea of the earbuds with great sound. Otherwise I'll probably go for the HF1 or Goldring 150. Or DT880 or SR225. Or ...

I should also have mentioned that comfort is important. I hear the Grados / Alessandros are sort of uncomfortable after some time? I tend to listen for several hours at a time.

About me: I mostly listen to electronica. I started my headphone quest about a year ago with the Audio Technica ATH-A700s. Then I sorta sprung for the KSC-75s, UE Super.fi 5 EBs, and JVC Marshmallows all at once about 3-4 months ago. After hearing the KSC-75s I've decided that this is the...

Anyone know the best way to let Xin know that I'm moving and he should ship to another address? I've tried e-mail twice but he hasn't responded to either.

Audio Technica ATH-A700: $131.95 Ultimate Ears super.fi 5 EB: $131.58 Koss KSC75 + JVC Marshmallows HA-FX33W: $30.78 Total: $294.31 ... and this is only my first post (and doesn't include amps/cables)! I hate, and love, to think what the coming years will bring.
