Walked out of an estate sale the other day with a mint condition pair  of Yamaha HP-1's for $15. I had no idea what to expect sound wise but I've got about 10 hours use on them now and I really enjoy them.  I've started reading this thread and modding the HP-1 seems popular but I think I'll enjoy them in their stock form for awhile before decide if I want to mod them.  
 
As I read through this giant thread I'll pay close attention to the mods but what I'm really hoping to find is info on how to properly amp them.  I'm surprised to see in the specs they can handle 3W's !!   For now they sound best with my old Pioneer SX-650.

Luck you, here they go around for 60-70Euro.

This reminds me of my ortho story. Got my yh-100 for about $8 in very good condition and knew nothing about ortho dynamic at the time. I didn't want to mod minw either because they were very good too. Mine sounded best out of a early '90s JVC CD player I had. Even though I had a 70's Sansui amp too. Finally I got a real hp amp and woah! Anyhow, sold them for $300 on eBay with some regret. Then ended up getting a awesome deal on some hifiman he5le for $420.

I think you did not get then for $8 on any on online auction sites.
Is it true YH-100 and hp-1 drivers are same?

I think he got them from a thrift shop or something.

How did you sell your YH-100 for $300? 

 

 

[MuZo2]

I should start selling some of my ortho collection.

So should I, I have a bunch of stuff that I don't want anymore and/or have given up on, like the TDS-5 drivers. I just can't seem to make them sound good so I want to get rid of them now.
 
EDIT: Made a classified for everything I want to let go.

A couple of downsides to vintage modding. Modded items aren't worth as much as the originals - which weren't worth much to begin with - and spare parts salvaged from units broken by excessive modding certainly aren't worth as much as complete, intact units.

It's why I said best offers are welcome as I have no idea what everything is worth!
EDIT: reduced the prices of most of the stuff in my listing. Tell me if anything's still overpriced.

Channel imbalance on my Argentum headphones detected. That or one of my ears is better than the other. Might be to do with the mismatched impedances of the Adastra drivers used.

So bad that you spoil T20v2 driver with superglue, otherwise i'll buy for stock.
All past week every day I used to check my T20v2 with hope that it will start to work again And on the weekends I decided that on Tuesday i'll come to work and disassembly driver to find problem area and try to repair it...
And guess what? When I came I plug headphones in, but one side still was silent. With last hope I changed cable for other one (before try it many times), put headphones on my head and squeeze them  my ears. And they revived!! Some distortion for few seconds and then clear sound!! ))))) Now they working already for 3 days without problems.
