I have just placed a Super 7 order for my HD800. I wonder if the tubes that come with the tube package would work fine with the HD800.. Also may start looking to replace my D18 DAC..would be looking for something in the 1-1,5 bracket. Any suggestions would be appreciated.
I recommend waiting to start buying tubes until you have the unit with the stock tubes and spend time with it...that way you'll be able to have a baseline and see what changes. ALSO, you can describe what you are looking for in tubes and get some help figuring out which ones might get you to where you want to go. I bought some NOS tubes while waiting for my amp that didn't end up playing well on the S7 for what I wanted (but luckily they sound GOOD in the Balancing Act).
So that's another recommendation of mine, if any tubes don't sound good in the Super 7 because of tone or presentation (not talking about noise/distortion/problems) and you can afford to hold on to them...they might sound good in other amps.
