I've also been looking at the Little Dots but there are so many options there. I've never heard of Pan Am and always assumed Woo Audio was out of my league. Is there some website where these options can be viewed all together?
What I'd really like is a nice warm sounding (preferably valve) headphone amp which also allows me to pass through the signal to my Marantz stereo amplifier.
Edit > I was right, Woo Audio is out of my league.
If you are considering Little Dot Amp don't bother with the other model other than LD 1+ for your Q701 i have LD 1+ and LD MK III both are modded for 6SL7/6SN7/12SN7 with External Power Supply.IMO Q701 with LD MK III sound nice but it's nicer with LD 1+.For the Tubes no need to buy those expensive EF91 EF92 and EF95 family all you need is the Cheap 6HM5 Yugoslavia for $5.00 per tube and you are set. and if you are willing to take it any further you can build the adapters for 6DJ8,12AU7 and for 6SL7/6SN7 but with all the tubes that i mentioned the 6SL7 or 6SN7 are the way to go.
