I have heard the ODAC is very analytical and not warm at all, sounds like something I won't like, some even say its not adequate for headphones but more for speakers..
correct me if I am wrong of course, the ODAC price is very tempting.
Do you have experience with the ODAC and CRACK? the AQ 1.2 is also around the same price isn't it better?
So you guys really think the speed ball is a must when talking about electronic music and deep bass? and you also say I need different tubes, in total it can sums up to almost 500$.. I really thought I could just buy the stock crack with stock tubes and enjoy it even bass wise.
In the future the speed ball is definitely in mind and also tube rolling but for now I want to get the most out of the budget, with the purchasing the best upgradeable dac and amp in my price range.
The stock Crack is musical. It's warm but not laid back or "tubey". The HD 650 are also on the warm side of headphones. Don't get me wrong : that is nice, I can listen to them for hours without any fatigue (like I get with, say, grados). So IMHO, I think you can get a clinical or analytical DAC. Now for the SB, I don't think it changed the sound signature of the Crack, only everything the Crack did well was even better : tight bass, excellent mids and precise trebble!
