I've had the HA-1 and PM-1 for quite a while but have almost exclusively listened using HD800's as it's the best I've heard them sound. However, over the last few days I've tried the PM-1's again. I don't know if it because the HA-1 has improved with time but the PM-1/HA-1 combo is really quite amazing. It's a great listen, almost tubey.... The HD800 takes some beating for micro detail and soundstage but the PM-1's are sweeeeet with the HA-1.
Hey Nigel!
I hear you regarding the HA-1 > PM-1 - that pairing grew on me, too!
Have you tried the PM-1 with a Sansa Clip+?
(I'm not kidding!) Forget about listening for shortcomings and just enjoy the fun factor - it's a very relaxed ride that invokes a lot of emotion - and it's thoroughly forgiving. Play your worst recordings - it's amazingly detailed but smooth in the highs, with increasing slowness as you go down in frequencies, until it's getting pretty sloppy in the low bass, but still punchy and again, very organic, natural, fun, immersive, involving, all those good adjectives.
You (or I, at least) just have to let go of the HD800 mentality and let it happen. It's kind of like watching a bad sci-fi movie - with a story line that breaks all the rules of physics - but lot's of fun when you stop judging it.
But the HD800 is another story - maybe because I've spent too much time with my LCD-2 and PM-1 on the HA-1. It's still a little too bright and fatiguing for my tastes, especially with the HA-1's ESS9018 DAC vs. something warmer.
Which cables are you using with the HA-1 > HD800?
