It is a prototype, remimbered? I worked all my carrier on high voltages, high power equipement (up to 25kV, and some time 50kV). Motors. step motors, big distribution panels, High power UPS with high voltages batteries bank, radar, high power transmitters, tubes and solid state, etc... Believe me, I know what electric shock risk is 😉
Second Pearl 3 pcb is working as well.

Yes, that’s why I put your name on it, and I like the rec color 😉 Even if the schematic was correct, a lot of things can go wrong with the pcb layout, parts selection, parts footprint, etc. For once there was not errors on this one 😉
I did pcb and built the two first Pearl design, and maybe 10 others phono preamp SS or tubes, including the Ono and the XOno. I wanted to try the 2sk209, always used the K170 in the other versions.
It is not my first rodeo, I did probably close to a hundred different pcb layout so far, getting there…

Well, life has a way of intruding into listening time... but even so, I did play a few LPs. All LPs I bought brand new and are all cleaned and well maintained.
I did play Suzanne Vega's Solitude Standing... which is a hard to listen album... she's recorded up front and it's obvious the soundfield is studio created. It's a little "hot".... but it has really good bass and shimmering, metallic cymbals when needed.
The sound over the P3 is EXPLOSIVE.
The way I see this preamp... is VERY FAST.
Now, with a stereo recording you have a lot of instruments all superimposed on top of each other, so to track it clearly, to hear the microdynamics that allow you to hear each instrument from each other the playback equipment must be able to track a very complex signal... fare more complex than a sine wave. I figure it must play back a square wave very well with little overhang, no pre/post ringing and a very fast slew rate.
The P3 seems to do this:
So after this, I had to make dinner, so I figure I'd just play one song off an old LP.... from the 70s... but, as it is, I played the entire first side..
Па, стојим поред планине
И посечем га ивицом руке
Да
The production is sort of prototypical grunge... a live recording... guitar is hard to the right, keyboard to the left, voices all over, drums and bass center back... sort of mushy when it all goes together.
Па, стојим поред планине
И посечем га ивицом руке
Па, покупим све делове и направим острво
Можда чак и подигне мало песка
Да
But the instruments and voices were well recorded and very natural, actually better than Suzanne Vega's LP which was done like almost 30 years later... The voices ( band and audience ) are clean, the guitar is excellent, drum kits, cymbals, etc... It's not an audiophile recording but an otherwise masterpiece.
I've heard this LP countless times but this time I was listening for it and I was surprised how much information came out of it (1).
Cause I'm a voodoo child
Lord knows I'm a voodoo child baby
So, tomorrow I'll flip it and listen to All Along The Watchtower.. (2)
And then I'll play Cream, Traffic, Steele Dan, Jazz At The Pawnshop, more Supertramp, The Clash, Dire Straits, etc... Actually, I should power up the A2s Maggies and the Entecs...
Now that ain't workin' that's the way you do it
You play the guitar on the MTV
That ain't workin' that's the way you do it
Money for nothin' get your chicks for free
Money for nothin' get chicks for free
actually, if I play Dire Straits... well, likely that'll be all I listen... ;-)
But it's written in the starlight
And every line in your palm
We're fools to make war
On our brothers in arms
Yowza.... if I could only play into the night without bugging the family... at least I'm listening to this over Tidal Hifi in my home office...
Tomorrow, tomorrow, I sure hope we don't get the Big One... because I got an awesome playlist that should really work out the stacks of DIYAudio stuff ( thanks y'all... )..
but believe in me baby and i'll take you away
from out of this darkness and into the day
from these rivers of headlights these rivers of rain
from the anger that lives on the streets with these names
'cos i've run every red light on memory lane
i've seen desperation explode into flames
and i don't wanna see it again
From all of these signs saying sorry but we're closed
Thanks...
(1) Mind you, the last time I listened to this Hendrix LP, it was with a much older preamp, different amps, speakers... even the turntable and cartridge have been upgraded.
(2) Can you imagine bringin a Jimmy Hendrix LP to a High End Audio Salon and asking to listen to it through a tube/class A system? They would need smelling salts. Could be worse... could be Never Mind The Bollocks... Now, that would be hilarious.

The P3 seems to do this:
- Very fast bass
- Very good macro dynamics - it actually jolted me of the seat at the start of In The Eye ( starts with a drum ). The song goes from dead quite to a drum... boom!
- Very good microdynamics... you can hear the differences between all of the instruments, clearly. The bass lines are clear, the drum playing is really good, her voice (and the fact it was very closed miked ) is obvious.
- Very quiet ( actually, the P2 is quieter, but this could be a case of the P3 having better high frequency response.... and now we're splitting hairs.
- Extended treble.. which actually is bad for a recording as Vega's which is too forward... her voice is a bit "tizzy". yet the cymbals are spot on. OTOH, Supertramp's Another Man's Woman was perfect.
So after this, I had to make dinner, so I figure I'd just play one song off an old LP.... from the 70s... but, as it is, I played the entire first side..

These are all very squishy words. ( IMPRECISE )
Too subjective for me.
squishy
adjective
ˈskwi-shēsquishier; squishiest
Synonyms of squishy
1
: being soft, yielding, and usually damp
2
: not firm, steady, or fixed : SOFT: such as
a
: LENIENT sense 1
b
: IMPRECISE
Thanks for the listening report, keep 'em coming!
A bit worried about your description of the treble. The diamond tweeters in my B&W's do not need more treble or "forwardness". Also curious if others also find the P2 to be quieter then the P3. Hiss is one area where my P2 could be improved upon (Accuphase phono board has 6dB more gain and less hiss than my P2).

Yes, thank you for your listening impressions. I find your report well written and clear, especially since I know the tracks you played. Glad that you could compare to the P2, and seem happy with the outcome 🙂. Keep them coming!
How goes it go…? Talking about sound and music is like dancing about architecture.
Funny…i presented my Masters af Architecture thesis as an interpretive dance…which may be why I’m still inknown 35 years later.
Thanks for posting your impressions and your comparisons.
It is always nice and positive to build a device and post about it - be it subjective impressions, objective measurements... or just sharing one's joy having it working LOL!
The world is large, there is place for everyone and every preference
Looking forward to reading you, and in fact "as ever" all of you as this is trully a great place!

architects... sheesh
I'm guessing that dance nicely bridged Goethe's freeze-thaw cycle theory?
By that standard, Hunter Thompson's notions on the music industry apply equally well to architecture and likely explain the dashed hopes of most every graduate architect.

It's definite: our Pearl 3 sounds better with the OPA2132P than with the OPA1642. That surprised me, because I've used many (ca. 45) of the latter in several preamps in which they sound really nice, and marginally more detailed in those units. Well, shows how circuit design can be affected so much by particular component choices, not to mention how the synergy of phono preamp, line preamp, amplifier, and other items in the chain can vary so much.
The chassis box I had selected was never shipped, so I had to place an order with another seller. Beginning to regret not just buying the ModuShop pair of boxes...

Useful Subjective Descriptions of fine sounding audio is quite simply no more complicated to do, or understand, than descriptions of fine tasting foods and beverages.

I bet you'll enjoy OPA1612 (on SOIC to DIP adapter) and OPA2210 (on SOIC to DIP adapter).
