How does this badboy compare to the Bottlehead Crack? I have a Crack that I built and I really like it, but I've never really compared it to anything other than my old 70s Marantz receivers. I'm thinking about keeping a tube amplifier at work such as the Ocean that's also running right now or this amplifier. (Or building myself another Crack) Any opinions? I could handle the anti-buzzing mod with new capacitors no problem. The power tube is the same as what I'm using 6AS7. The input tube is a 6SN7 which I have tried in my Crack with an adapter. I found it to be less impressive than the 12AU7 tubes I have (but I only own one 6SN7 tube to try out.) Just curious if any of you have listened to both?
I've got Beyerdynamic DT990 and DT770 (both 250 ohm) and Sennheiser HD650 (300 ohm). I don't use the Sennheisers often.. they're not comfortable and don't produce enough bass for my liking.
no sense in getting the DarkVoice over the Crack, surely not for these high impedance headphones.
If you want a warmer presentation and more bass, opt for the Bravo V1 / V3 , Indeed G3 or the Aune T1 .
While the DV and Crack are better sounding, I wouldn't get any of them for office use :P
Will the Aune or Bravo give as warm a sound as the Darkvoice? Are they really comparable in sound quality?
I have a Bravo and am under the impression that the Darkvoice will be a significant upgrade in sound quality.
The Bravo produces a lot of gain, so much that most headphones use very little volume on the knob and anything pas 5-10% will be far too loud. That being said, the Bravo is an awesome amp for the price. However, it is a hybrid tube amp and not an OTL.
I do not have an Aune (T1?) but that is only a tube DAC, the amp portion is solid state.
Hopefully this helps a little bit.
Do you find the Bravos' gain leads to a lack of volume control, with so little room to move?
I'm a little confused/suspicious by this tube DAC idea? But I guess is colors the signal in a similar way to a tube amp. If anyone can confirm the Aune T1 is a nice warm sounding amp I might grab it for my desk as the Darkvoice is really too large for a desktop amp.
The aune T1 is pretty nice for the price. I cant really complain about it, especially if you can get it in the low 100$ range. But my friends bottlehead crack completely blows it out of the water in terms of warmth and especially rendering of the low end.
The standard tube it comes with "upgraded" is just kinda meh though, so you might want to consider an upgraded tube.
Yes, my main gripe with the Bravo is that there is little/no volume control.
It's a cheap tube amp and a great place to start, but it has so much gain that it makes finding a comfortable volume level a chore.
The Bravo amps are geared towards high impedance headphones.
Efficient headphones are a poor match for these, due to the high gain of 30dB .
That said, the Darkvoice is an OTL amp, which is also geared towards high impedance headphones (120 ohm at least).
If you have low impedance headphones than you should defo look elsewhere.
The Litttle Dot I+ , for example, is a good place to start.
you can make it sound pretty much the way you want it ..it's all about the tube you will roll (Amperex or Silvania -"green hornet" will give you the warm -"tubby sound" ,you can also roll Siemens or Russian "rocket/reflector "for up front and very natural effect , headphones will make a big difference
Aune T1 with the re-cap upgrade (Darkvoice or Crack-advantage Crack ) sounds pretty amazing,it's all about the tube in the end
