Yeah, I might need those. Some folks said the knob even gets hot to the touch after a while. I don't know if they're exaggerating. Anyway, I pulled the trigger on the Bifrost Uber and the Valhalla. I got the last Bifrost Uber on Amazon (yeah, I'm that guy). Probably won't get it until next week, but I'm excited! Going to call this an early birthday present since my birthday is next month too.

My Lyr makes a great hand warmer this time of year.  -34C outside right now.

I was in Alaska last week so I know how the cold feels. I currently live in Hawaii so I don't exactly need heat, though. Thank goodness my apartment has utilities included. I'm going to need that AC a little more.

 

According to the Schiit website, the Valhalla tubes are more expensive than the Lyr ones. Is it because they're more suited to the amp?

Because the Valhalla is an OTL and needs 4 tubes, the Lyr is hybrid and needs 2 tubes.

I wish you all the best, I´m planning to start my year listening to this great cans, I already got my favorite CDs ready for tomorrow and on top of my new year´s resolution is to get a matching amp (BTH Crack)

Aune T1 or Epiphany O2/ODAC for HD650?

At least with the JDS O2/ODAC, you'll get bass distortion with the HD650 because of the output impedance of the O2.

Wut?

It only happens on high gain. 

 

Me to JDS: "On high gain, it is breaking up with my HD650. The bass gets crackly and distorted, especially around 60hz at -10 db. Other frequencies give it trouble on some songs too. I had to wait to get another amp to see if its definitely not my DAC and not my headphones. Is this just the O2 being maxed out or is there an issue with it? With another amp, the system does not have that problem... This doesn't seem to match up with any reviews I've read of the O2."

 

JDS to me: "This occurs with O2 when using a strong source/DAC with some headphones. You simply need a higher voltage AC adapter to use high gain. More information can be found on the instructions guide."

Been through all this before,

 

High gain is not for DAC source (with DAC output 2V use gain 2x or less)

Higher voltage adaptor is irrelevant. JDS should know better.

Yes, but it seems valuable when someone is asking about the Odac/O2 w/ the HD650, right?

Doesn't matter what headphone you use, high level source -> use low gain.

I still have a hard time deciding the Magni or Vali to keep with the HD650. The Magni has a brighter sound which compliments the dark/warm signature of the HD650 pretty nicely, also has more speed and adds some sparkles to the treble. The Vali adds a darker/warmer signature to the HD650, but has MUCH better bass, which sounds more controlled and has a larger presence, adds the wetness/reverb quality of tube amps, sounding more organic and less robotic vs solid state amps. I love the Vali, but it almost makes the HD650 too dark/warm, too slow, and almost makes me fall asleep every time I listen to it because I just want to close my eyes and enjoy the music.

 

Can anyone compare the Vali and Bottlehead Crack w/ Speeball, whether the additional x3 times the cost is worth the sound quality upgrade? Does it sound more warm/dark than the Vali? Does it have more speed? Does it have as much microphonics? Does the treble have a better presence? Is the soundstage larger? etc

post #15060 of 36844

For me, the crack with speedball is supremely good. The Vali is a very nice amp for the money but head to head simply can not compete with the crack. YMMV
