Okey dokey. I have maybe listened to this now amp for approx 2 hours and A/B`d with my P3 and Westone 4`s.
I retract my initial statement of after 1 track this amp is no worse than my P3.
My new statement is, it is different and depending on what you are "used" to then that is why I am going to make comments on what I am "used to".
I am used to a laid back spacious sound with superb instrument separation and soundstage (P3)
The BH is not, it is more forward and condensed which I have quite liked for dance music but as I am not used to that I would need to brain train to that signature.
If I use the LF switch I think "Ahh that`s what I am use to" but it makes male vocals sibilant somewhat and seems to affect he high region. That is what I find with the LH switch, it also adds a touch to the highs.
I bought my P3 from Spud Harris (You will probably know who he is) with nearly the opamp configuration I have in my sig which I modified also with his help.
I have also purchased the "Top kit" from another well known Headfi guru but that didn`t compare to the setup I had.
With the above in mind, this amp was up against stiff competition and although does things well it just falls short for me. The only other amps I have had are the Fiio E5? and Gary`s Pav2.
This is all based on an Ipod 2nd Gen Itouch, my W4`s (MTPC coppers didn`t fair well) and 2 LOD`s.
No doubt this is a capable amp and paired with a set of IEMS or cans that have good synergy then it will please quite a few. It has more power than you will ever need regardless of what you use imo.
I will keep this as a backup for my iBasso but if you can get a 2nd hand P3 (discontinued) or another rolling amp with my configuration then you are not far away from audio heaven.
