I had also made a 2 tiered blued steel table with copper legs, a perforated steel shelf with ball bearing slides and a zebra wood and aluminum headphone stand for the hd800's to go with this. If I have a good day I'll try to take pictures of it and post it.   Thanks again for all the nice...

  I started a thread with another photo, but here is my bottle head crack with speed ball Chassis that I  made from aluminum and stainless steel. I already had the Crack board from another chassis.

Thanks everyone!  

 I © 2012   I know there is a big thread about the Bottle Head Amp. I thought I would post this one, it's the last project I made before I became too ill with what a neuromuscular problem, so it may be my last project like this. I already had the board from another Bottle Head Crack with...

I have had the sr80, 325i, rs2, and rs1 at the same time. I was glad to have had the chance to spend time with all of them. They were different enough that I had many pleasureful evenings comparing the sounds of each of them, although they sound similar enough that I would be happy with only the...

Thanks Doc!    

I am also a fan of the 5998!    Doc, I remember reading that the 5998 lowers the output impedance to about 50 ohms, is this correct?   The 5998 sounds great paired with a tungsol black glass and a bugle boy 12au7a.

You are correct! I meant to say that it might work better with a tube amp with an output transformer, since my bottlehead is an OTL and I might just be squeaking by with the 50 Ohm output... Put an edit in the last post to fix this, thanks! (another correction:Doc from Bottlehead just let me...

I posted this in the modding thread but I thought I would post it here also.   The DT1350's bass really came alive when I use a bottlehead crack/speedball with a Bugle Boy 12au7a and a Tung-Sol 5998. I am listening to them now. When I A/B them from the headphone out of the Nuforce HDP vs the...

  Maya Tlab,   I think the graphs match the sound that I have heard on the p5 and the dt1350 quite well, as well as showing the midbass bump witht he lack of extension that some have reported on the hd25's.   If you look at the posted graphs there is a slight midbass hump in the graph...

I found the dt1350's sound much fuller with nuforce hdp > bottlehead crack with speedball using a bugle boy 12au7a + tungsol 5998 (I believe the 5998 brings the out put impedance to about 90- 100 ohms)   It sounds significantly fuller than the hdp by itself, my macbook pro headphone jack, or...

Whoops - double post...

I am curious if the frequency fluctuation is engineered into the design (as in: "later vs earlier" versions) or if this is just the result of normal manufacturing variation.

Quote: Quick impressions:   Both sets are very smooth, but a different presentation. If you A/B both then the dt1350's will have an obvious drop out in the upper-mids, lower treble and the Dt880's will be bright and missing some bass weight. When I become accustomed to the signatures of...

To my ears, with a nice setup, I found the HD800's to have strong bass, beautiful sweet mid range and I did not really hear "the dreaded 6k peak."   I finally received my graph:
