Headamp Pico Power Impressions Thread - Page 2

Thanks for the clarification Justin.  It isn't really an issue, just minor OCD on my part probably.  I did adjusted the gain settings as I said and it was fine.  It is now an integral part of my system and I am very happy with it by the way.

I am pretty pleased with the how low I can go on the pico power before any inbalance.  Practically to the point of silience.  This is with iems.

At least on my unit, Justin's parts select is paying off.  Ran a quick test in my office, actually two.  The first was testing for the wrong thing.  The second test measure pink noise with a small mic inserted into the left headphone  (measure 85db) with the volume at the half way point.  Then I dropped the volume until it was at 42db, about 4db above the room's ambient (roughly 8 of the grip ridges).  Moved volume back to original level and played with the mic position on the right side until the meter showed 85db.  Then I dropped the volume to the same lower position I used earlier on the left channel... the meter 43-44db.  Not a bad match.  Unlike an audiologist, I don't have the ability to do real ear measurements with IEM, but I did drop the unit down to low gain, fed both channels the same signal and they seemed (to my ears) well matched. Overall, I am very impressed with the Pico Power.

It actually keeps sounding better an better to me.  Really a gem.

Wish I was in the market for something like this when the bulk of pre-orders was occurring.  I'm impatient, a character flaw, I know.  I want/need something right now, so I have an RX MK3 on it's way to me, but I know at some point after the crush of pre-order shipping is done, this is an amp I will want to get.  Please keep the impressions coming guys

I turned away from the 9V battery or even any standard battery amp because it seemed too painful to have to exchange batteries/recharge etc. 

How is the comparison with the Lisa III?

Thanks for the wonderful video, Phototristan. I enjoyed it.

Thanks for the impressions En_R. 

Looking at the Pico range, if audio quality comes first, using low impedance headphones, would the PP be the choice?

I bought mine for use with my iems.  I had a pico slim which was outstanding but the small form factor of it was not useful for me.  As I mentioned in an early post the POT on my pico power does not demonstrate low volume in-balance issues with my particular iems (1964 Q4s).
