As I looked into this more, I realize that the E11 cannot be charged while listening. It runs only on battery power. Since I will be using the ELE DAC and amp at my desktop (I don't even own a laptop), portability is not a requirement. Having it connected to a power source while listening is actually preferable. I have noticed that Bravo amps have been very highly praised in this forum, specifically, the Bravo Ocean. However, on Bravo's website, I also see the Bravo V2 which seems to be identical to the Ocean except for the metal case. Since the cost of the V2 ($69.99) is only a bit more than half that of the Ocean ($129.99), the V2 just might be a great buy. Has anyone here been able to compare these two to see if there are, in fact, any sonic differences? What does almost twice the cost provide other than a better housing? Thanks!
A hybrid tube amplifier is the way to go. I have an Indeed G3 hybrid tube amplifier like this one:
The seller used to have those on auction until a few months ago. I got mine for $87.66 including shipping, in April. They got as low as less than $70 in some auctions. The sound of tube+solid state (that is why it is called a hybrid amplifier) amplification is superior to the sound of just a solid state amplifier. Besides, you can get other tubes for your amplifier that will make it sound different with each tube.
With these Bravo and Indeed amps, quality control may be an issue. I started having problems with the volume potentiometer in mine after 3 months. In spite of that, it has been a good investment.
