@judge, if you're ever around where I live I'll buy you as much beer as you can drink that night. I owe you a few as well

Mine definately did not sound compressed out of the box, quite the opposite it sounded very dynamic (actually frequency response wise it sounds fine to me though its supposed to be limited in the highs, which I don't really like too much highs anyways - maybe you need some brighter phones).  And as the tube started to break-in the sound became much smoother.  Compared to the output from a receiver, quite a big difference.  The source could be the problem.

After spending about a day listening though the stock bravo v2, i'm not particularly impressed with the sound. Granted i'm using a pathetic old clip+ as my source and phones that do not really need amplification, but the bravo seems to worsen the sound by make the frequency response more compressed. The lows and highs seem to roll off very early, compared to when unamped. So this resulted in cellos starting to sound like violins

. Also, the bravo is probably not very usable with iems since they hiss pretty badly when plugged into it. The only improvement that i noticed was a slight increase in soundstage especially when listening at lower volumes, but not exactly by a lot.

If I ever get back that way, I'll definitely take you up on that... but you owe me nothing. I got a better idea: lets go to Amsterdam and I'll get a prescription for my "glaucoma" and we'll drink until the dykes collapse... and the dams burst, too.
 
Oh yeah, I drink German lagers, when I drink beer. The best I can normally get are St. Pauli Girls and Becks. One day, you and I will discuss the availability of Hacker-Pschorr... I made it to Oktoberfest (Munich) in 1979 and 1980 and I haven't drank much American beer (except Sam Adams) since.

My Power supply Died in a Storm a while back. What kind of power supply am I looking for to replace it? I know the stock one is supposed to suck. 24V 1-2A? Switching or not? Any links to tried and true ones? 
 
Thanks!

You were kind enough to help me out too, so I'll chip in and get you all the glaucoma medicine you need if you come this way

You can't just cut a lead on the tube led. You must short it.

I found a pdf doc from a Rockgrotto forum guy, there's a schematic, it shows LED+resistor are shorted yet in the Indeed amp.
 
Edit: my G2 was 76$ shipping inc.

After another day of listening through the bravo v2, I seem to be gradually enjoying it more.
Its merits are most obvious when listening at low volumes. I no longer need to turn up to the volume higher to hear the details and open up the dynamic range and soundstage, which is great since i'm always trying to keep the volume as low as possible for the safety of my ears.
 
The "compressed frequency" still seems to be present though. Its kind of like the ends of the frequencies are gradually rounded off, and strangely, more so in the low end. Some stuff sound brighter than they should be (which is weird since i thought tubes usually add warmth), but theres not exactly a lot of sparkle either. Somehow i have a feeling its better than yesterday though. Maybe burn in happened (to the unit or my brain).
I have a this will probably change for the better when i stick a better tube in though.

Get an RCA cleartop pulled from a conn and I'm sure you'll find the warmth :)
Like this one: http://cgi.benl.ebay.be/1-Tube-12AU7A-ECC82-CONN-RCA-Clear-Top-Tested-/160485871660?pt=Vintage_Electronics_R2&hash=item255db4102c
 
But for that one emissions are a bit off. Good ebay seller though

Hmm i thought cleartops are supposed to be bright? Their name seems to suggest so

(edit: ok i realized how stupid that was)
I did some reading at audiotubes.com and figured the mullards are supposed to be the warm ones.
I won some RCA long grey plates on ebay for a couple of bucks a couple of days ago. But since they're shipped internationally I won't be expecting them too soon.
