Hi,
I am by no means, familiar with the world of audiophile equipment but I am a huge music enthusiast and I contemplating the purchase of a Bryston BDA-1 DAC. However, I was disappointed to learn that there's no native headphone output. The in ear monitor's I am planning to use are the Ultimate Ears 18 Pro custom in-ear monitors (http://ultimateears.com/en-us/products/18-pro). I was wondering what preamplifier you might recommend for use with these headphones and the BDA-1.
