Fritz, a couple of OPA602AP on their way to you tomorrow..... got them in a jiffy bag will ship tomorrow. Much the same performance as the OPA602BP but cheaper.... I'm keeping my stash of BP for a rainy day.
Let me know what you think of them in the WNA and please let the amp warm up for 3 days before fully evaluating them.... they get better the longer the amp is powered up.

Thanks
But - please give the LT1056/LT1022 a chance - free samples for LT1056/LT1022 are open (2 pcs) - last both days I had some sessions ....
The LT1056 sounds warm and cold, sharp and soft, analytic and natural - so as the sound-engineer has done his work
Highlights Roger Waters, Amused To Death Deeeep natural bass
Pink Floyd, Final Cut Good micro dynamics, very subtle in background (slapping shoes, playing children, ..)
Today I got my "analog-audio cookbook" from Horowitz/Hill

Pete Townshend"Face the face" (in german we said "fetzt so richtig") deep bass "grummel " and brutal drums
Sinéad O'Connor"GOSPEL OAK" had rare heard this so natural and realistic
I think this are twice effects - one the LT1056 second - my K701 nearly burned in
The K701 is one of the best headphones I ever heared!

Yesterday I got samples of LT1022
My first (subjective) look and feel - the LT1056 sounds better - but I will give the LT1022 a chance to burn in

additional listenings ....
LT1022 sometimes a very little bit muted leadsinger a bit more in background, quieter - but background sound a bit louder clear sound
emotionally I missing something but I cannot say what
LT1056 sometimes tiny strained in treble at sizzle cymbal, LT1022 does not.
This statements are subjektiv and emotional ......
I rate LT1056 emotionall prior to LT1022, but very close
I found in my treasure chest some .... OPA 655 http://focus.ti.com/docs/prod/folders/print/opa655.html 400MHz UNITY GAIN BANDWIDTH LOW INPUT BIAS CURRENT: 5pA HIGH INPUT IMPEDANCE: 1012(ohm) || 1.0pf ULTRA-LOW dG/dP: 0.006%/0.009° LOW DISTORTION: 90dB SFDR at 5MHz FAST SETTLING: 17ns (0.01%) HIGH OUTPUT CURRENT: 60mA FAST OVERDRIVE RECOVERY
have anyone experince about this?
and some too AD845 AD825 (SOIC) OPA627/37 OPA227/28 OPA604 LT1360 LT1363 and ... whats about this?

Thanks - now the OPA602AP is inside
My first short impression without burn in or longer warming up and only one CD "PF FinalCut" ...... nearly perfect - detailled, good micro dynamic .... more later .....

It's really a pity that David can't get you a MKlll board Fritz, you're so passionate and dedicated to get the best out of the old girl Did you ever put the cascode PSU together?

after long time David replied - I have an "eye" for a MKIII board and a DC protection board too - and then I will make a new amp with cascode PSU too - and without splitter?
But I am in a Catch-22 situation - should I make a new WNA MKIII or buy a Graham Solo - but can anyone help me to detach my dilemma

Fritz, you need both. Your mind will NEVER be at rest until you have them both next to each other! I think you deep inside even know what the end result will be. You are a victim and slave of your thirst for knowledge! EINFACH KAUFEN!
