I love my RAAL SR1a phone. I recently heard some of the very best headphone amps and phones at a meetup. Just incredible stuff and some setups approaching $50k.
However, my 2 systems that are 2-channel are always better than the phones. I have been breaking in 2 DACs recently, the Schiit Byggy and imersiv D-1. These both have massive soundstages and do all the things that are considered great for a DAC. On my 2 channel systems I can appreciate all of these attributes. On the phone some of these attributes are not as pronounced. For example, soundstage is a hard one for headphones. My SR1a has the largest soundstage of any phone but it is not 2-channel.
My 2-channel has a purpose, and I will use it for that right now. The family is going to sleep, and I have more work to do. Got to turn off the 2-channel.
