I got rid of all my 2-channel stuff a few years ago, just Sennheiser HD800 headphones through MacBook, Schiit Lyr and Bifrost. Not bad but I missed the presence of real speakers moving lots of air. Earlier this year, I decided to set up a 2-channel system and started reading reviews. I've had some good stuff over the years (ARC, Cary, CJ, Levinson, McIntosh, Sonus Faber, Harbeth) but wanted to look at a simpler and less costly system. My short list of integrated amps was Parasound Halo, Hegel 160 and Peachtree 300. Ended up with the Halo because the reviews are good and one came up on Audiogon at a great price. Also, it bothered me a bit that there were so many Hegel 160s and Peachtree 300s up for sale on A'gon and elsewhere. Good products but why so many for sale? I'd never heard of Salk but ran into a couple of reviews, looked at the website and the Audiocircle discussions and basically found a philosophical fit. Ordered the Song3s as a result. Bought the ERC-3 to replace a Marantz universal player, which I still use for DVD/Bluray. Added a pair of D Murphy AA monitors just so I could start listening. Everything sounds remarkably good, even listening off-axis. Expect it will sound better with the Song3s in place.
