Hello!   About a year ago I bought my T1 to play with Bottlehead Crack OTL amp. I wished to build Crack and was in search for a good pair of headphones to match with this OTL. At that time I had a Schiit Modi/Magni combo and thought Modi would be enough for my system. So currently I run my...

Hello everyone!   For about a year I am happy with Beyerdynamic T1 on Bottlehead Crack!!! Thanks to everyone who suggested me to buy T1 for Crack! Although recently I feel the amount and impact of bass for me is not enough.  I wander will Speedball Upgrade fix it?     And... what do you...

I guess I will wait for a week or so, to become familiar with pure Crack sound.  After that would install Speedball Upgrade. Hope to hear the same level of improvement as in case Magni->Crack =)   By the way, is there anything from Bottlehead to upgrade from Schiit Modi?

  To make it clear. The last phrase I wrote comparing change of sound after moving from Magni to Crack. Mids and highs changed a lot in a good way, but bass changed not to the same extent. 

Thank you, now I get it! Why do I liked D600 with Crack -- it has much less prominent bass, healing overall balance.    But T1 with Crack is just awesome. The sound is stunning, I could not stop listening. May be it is due to my first experience with tube amps (Shiit Magni, Audinst mx2, Fiio...

Speaking of soundstage size, HD700 with Magni is similar to T1 with Crack (with Magni it was too small).  It's hard to imagine how big would become soundstage of HD700 or HD800 with Crack...    And one more interesting thing: it is said that one need high-Ohm headphones... BUT I have no...

Spent today 7 hours to do all soldering. Likely no mistakes.  And yes, with Beyerdynamic T1 it sounds great!

Small question here: How should I describe Bottlehead Crack OTL Kit at customs for calculation of TAX? Amplifier? Tubes and cables?

About half a year ZMF were in the box. At that time I tried Hifiman HE-400, Sennheiser HD700, Beyerdynamic T-90 and was pretty pleased with that sound. But about a month age I took ZMF back to my everyday use... and was really amazed about its sound signature.  With Schiit Modi+Magni it was way...

Hello to everyone! Sorry for the stupid and probably frequently asked questions.    For now I used dynamic and planar-magnetic headphones, and have interest in electrostats.  Currently I have Hifiman HE-400 on Schiit Modi+Magni, followed by Beyerdynamic T1 on Bottlehead Crack OTL.    I was...

Thank you! Could you comment on this article of comparison between T1 and HD800 http://www.headfonia.com/hd800-t1/ ? Yeah, that is a good Idea! If I only had enough money... And I generally prefer to have only one pair of headphones. 

What is more interesting now, is changes in sound.  Did anyone compared Crack with Magni? Or oven better Modi/Magni vs Modi/Crack ?

Ok, moving forward! If one would compare T1 and HD800 on Crack SB? Are both of them significantly better than T90 and HD700?

I just found one pair of T1 for 700€, probably could try it.  Especially if they are significantly better than HD700(500€) and T90(400€). 

Right now I can still choose which headphones to use.  So, the basis is Crack + SB.  As for headphones I could afford some in the price range 500€, where Beyerdynamic T90 and Sennheiser HD700 are.  Are there any other better headphones within this price range?  And which headphones would...
