Greetings, Does anyone know if the newly revised Total Bithead has an improved DAC, or is it only the amp circuit that's better? Thanks!

Simple question- Is there a way by looking at the circuit board on a Bithead amp to tell if it is a regular model or a Total Bithead?

First off, I'm a noob....so my astonishment at various things will be no news to all you more experienced folk After upgrading from the SR60 to the SR325i, and then finding them a little too bright for my tastes (depending on source) even after a 40 hr. burn in, I contaced my dealer and he...

Let me start by saying I'm new to all this, so I'm sure some of you will have a "duh" or "no s---" reaction to some of my statements/questions here... I've picked up the SR325i recently, and have been listening to it straight out of an iPod at first. Great sound, love everything about it...
