I received my HP-P1 from Moon Audio on Wednesday and am enjoying this greatly! Two years ago I took the plunge and bought an Ipod Classic 160G. I LOVED the capacity of this thing and loaded it with my entire collection of lossless CD’s. And I have been dissatisfied ever since. I have good headphones (Audio Technica W1000’s and Etymotic ER4-P/S). They tend to be detailed and analytical and they expose the flaws of the source. So, I got a line out dock and a Corda HA-1 amp and things improved a bit at the expense of portability. But I was never fully satisfied. The combo was, frankly, boring, flat and lifeless. My classical collection suffered most as I just wasn’t moved when I played them.
And now, what a difference! I noticed it right out of the box. I started with my Ety’s and I was like, wow, this is what this music sounds like! This is what these fabulous earphones are truly capable of! I am now revisiting my wonderful classical music collection as though for the first time. The amp powers my W1000’s well and good. But it seems like the pairing of this unit with the Er4-S is truly a match made in audio heaven. The music is richer, less analytical and more dynamic while preserving/enhancing details (searching for words here). The Ety’s were a set of sleepy phones that have now come to life. So, I recommend this for anyone with the Er4-S. And now I know what I have always suspected: The latest generation Ipod Classic DAC was the weakest link (the Corda is a great amp by the way, It serves my computer rig now). I had been hoping that the Ipod DAC could do what it simply could not do, was probably never designed to do, which is deliver truly audiophile sound through the dock to a decent amp. It never could. Problem solved. My classic is now a first rate transport for a wonderfully matched DAC/Amp magically mated to my Ety’s.
Another winner with this dac/amp is, of all things, my Cambride Soundworks Model 88 table radio! Go figure! I can clearly hear a significant difference when connected through the line-out of the Fostex. Better bass and detail (like with the Ety’s). I certainly didn’t expect that and it speaks to the quality of this device.
Ironically, now that I am enjoying my Ipod like never before I am now presented with rumors about Apple discontinuing the Classic! I might have to go out and buy another as a back-up!
