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.
I'm suspecting that the stock china tube is main the culprit. Will review it again when the rca tubes that i ordered through ebay arrive. Will also be looking forward to picking up some diy skills and modding my bravo when i have the time. Hopefully that will change the above impressions.
