Couldn't live with 105 as all-in-one hub for fidelity and vinyl reasons. I'm lean to being a no frills sort. Not even have a balance control on my preamp. I have had my 105 over a year using it for CD/SACD/DVD-A/Bluray playback and streaming PC, server and cable audio. Edgy, bright not smooth...digital sounding. Then I added an inexpensive tube buffer after the 105. WOW!!! Maybe the tubes and/or maybe an impedance thing? I promise you adding this magic box after the OPPO made for real people playing real instruments right there. Open, quiet background, detailed, natural dynamics and pinpoint placement. No digititis. The opposite of the muffling tube buffers of old. No one here will listen any other way now. Even bought a second buffer as a backup and all my high price modified CD friends are jealous of the bang for the buck results!
