I've made contact to Freid and he suggested to change ground lift jumper position.

I had a same issue with my 109P when I use RCA inputs. Weirdly, It has been solved by using XLR inputs. Ive been thinking asking about this issue to Freid, but not yet.

bookmarked the site.   Fantastic job!

Hi all,   I've got my G109-P and enjoy listetning to them. I may write some impressions near future.   Anyway, I want to say here, if you are interested in LP product and you don't have local distributer in your country, I recommend you to buy them directly from LP. As for those have looked...

Wow! Amazing to find thread for Shiros(h)ita headphones!   HP11 is the shop original version of HP10, not particularly a new model.   HP10 has more soft, warm and somewhat dark characters compared to 900st.

In my measurement, K240 have multiple up and down between 1k to 6khz, so some may feel they lack energy on mids. Overall they are good headphones, but not spectacular. I personally like them, but I won't recommend them strongly to others, since they are bit hard to drive also.

If you want better Hd555, HD650 is right for you. RS-1i is pretty good can, but it sound different from HD555. It has more treble and much bright sound. If you want something really different from HD555, you probably like ultrasone PRO750 or DJ1PRO.

Sad that it's gone out of production in Japan. I think I should get one of this before it won't be available.
