And our winner is…

ROFL!!! I can only wish that was my last boss's head at the business end of that sledgehammer.

No worries...I'm better now. Fleeting fantasy only.

I crack up every time I remember that scene where Jack Nicholson is in that mine, pounding away on that rock, with the prospect of doing that, ALL DAY LONG!!!!

A rather interesting movie (Goin' South) with a surprising cast.

So my 'Settling in On-clock' has just been re-started, yet again after I installed the 2nd set of our latest iteration of CCS's.
And as I type this they have ≈ 3-4hrs of running time.

And yet again, of course this assessment is only initial and will need more time for a 'full' eval.

Even so just now I heard some acoustic rumble from the room as a BAD (Big A**ed Drum) 'charged' the acoustic space of the entire room with low freq energy. And as it dissipated the subsonic harmonics shook/rumbled my head and lasted for several seconds.
Most impressive I must say.

Still the SQ is behaving much like it did after the 1st set of these latest CCS's were installed, in that it seems like it will take several 10's of hrs before full blossom action will be reached.
But as usual there could be 'surprises' along the way.

More later.

Did you get your clock from the set of Groundhog Day?

 

[johnjen]

Well now that you mention it, I did find the 'best deal' on a suitable clock at Tyme Portals-R-us.
They had a unique "ANYtyme" return policy, due to their "Tyme Loop" which is an unfortunate 'feature' of their tyme algorithm.
Their marketing verbiage read, "ANYTyme is the right Tyme for anything.

And because they paid me more when the clock was returned, than it's original purchase price, the longer I waited the 'better' the deal.
So I figured what's not to like?

Well, other than that pesky time looping behavior where it never started and never ended, it just kept going and going, and going…
hahahahahahahahahahahahahaha

But if you'd bought it at a later date and subsequently returned it before you bought it, would the acceleration of price appreciation apply proportionally or logarithmically? Or inversely? This is all so confusing....time for me to have more coffee.

 

[johnjen]

I figured out, all on my own mind you , that if I returned it before I bought it, one of 2.5 things might happen.
#1 I WOULD have to pay for it so that wasn't a 'Really Good Deal' (RGD), IOW I'd wind up screwing myself out of a RGD…
#2 It would be like dividing by 0 and the reality as we know it would collapse in on itself and so no one would be able to find a RGD ever again, nor even care!
#2.5 Or I could claim I was the savior of mankind by NOT dividing by 0 and collapsing the wave (good bye) function…

And besides the RGD had WAY more motivation going for it, because as we all know, us audiophools ALWAYS are looking for the RGD, consequences be dammed…
hahahahahahahahahahaha

So a SQ update on the Purp-Amp.
'The Clock' is in the 30hr range and the SQ is making new strides yet again…

Yeah I know boring…
Does it ALWAYS have to do that, I mean talk about a broken record or what?

But in the name of SCIENCE I must push on ahead to take these SCIENCE experiments to their full completion.
And I keep on making them all the more complex and involved, which in turn keeps extending their completion date.

But I can see light at the end of this tunnel and it appears to be getting closer.
I just have to keep reminding myself to NOT stay in between those 2 tracks.

And all of those previous posts about EVERYTHING continuing to step up and over the previous SQ peaks, by all measures, continues unabated.
Which is a continual source of delight, so I can say these latest CCS (Constant Current Sources) iterations are a keeper.

Which leaves but just a few experiments left on 'The List', with the most notable being a tweako set of custom buzzword laden output xfmrs.

Right now however the music calls to me, like a sirens song…

Time to get a spectragraph.

I thought @Tjj226 Angel was referring to this:

 

[johnjen]

So the Purp-Amp has reached a degree of midrange presence that makes all vocals (foreground, background, secondary, chorus, duets etc.) stand up and be noticed.
It's not that they stick out, but that their 'place' in the soundfield is now much more prominent, forthright and engaging.

And it's not just the vocals, but all the 'voices' in those 'magic-in-the-mids' have stepped up their game and now deliver a more involving and captivating musical experience.
HB&W, T3 - (Head Bobbing & Weaving, ToeTappingTime) all are in full engagement mode now.

Also there is an added 'punch' to all 'voices' that have a 'hard leading edge' to them and some are rather surprising in the amount of added 'whack' that they can deliver.
And this at just short of 50hrs, with expected blossom action in the next day or 2.

And it seems as though SDSG (SuperDuperSuperGlue) has started using a brand new fresh tube of superglue now with 'extra' sticky stick.

So right now I'm at 75hrs which is in the 'zone' for blossom action…

EDM (Electronic Dance Music) and OVERWERK in particular, is most impressive as it has smack (up side my head) and plenty of it.
As does classical with 'strong bass'.

But the MitM (Magic in the Mids) is where my attention is drawn to focus upon.

When the extremes (bottom and top end) are 'close' then, when the MitM 'couples and blends in' and becomes the center of focus, is when the extremes are more fully appreciated as they provide the finishing touches to where 80+% of all the music resides.

A friend recently noted that during certain portions of music, the bass reaches all the way down his spine and rattles his entire chest and abdomen.
While listening on his tweako setup with his modified 800's.
I commented that I still am not sure how that happens (having experienced it myself) other than our acoustic sensory processing capability must be 'filling in' with the 'missing' associated visceral components of sub bass.
Think of trouser flapping bass, without the trousers, nor the flapping…

In fact I'm experiencing said "bass without the trousers, nor the flapping" even as I type this, while listening to the Grand Canyon CD bcowen posted just up there ^ a ways back.

"Flapping" can be be virtual. I read that on the internet.

I *do* remember hearing that CD for the first time in a dealer's showroom in Cary, NC with the Audio Artistry Beethoven speaker system driven by some big honkin' Jeff Rowland amps. Sadly Audio Artistry is no longer a going concern, but the design mind behind them was none other than Siegfried Linkwitz. There were two main panels and 2 dipole subwoofers (meant to be placed right against the side walls) and you needed a pair of accomplished stereo amps at about 200 watts each (or preferably, four 100+watt mono amps) to drive the system properly. But set up properly and amplified properly, the in-room bass response was flat down to 20 Hz, and a -3dB point at about 16 Hz. Ever heard bass notes that make you almost nauseous? I mean nauseous in a good way, like "DAMN! How much will this cost me?" kind of good way. LOL! That CD goes way on down there, and if the system will produce it, the sheer power of those bass notes provides great big huge audiophile goosebumps.

Those speakers in their multi driver configuration reminds me of the Genesis line of speakers.
Not exactly the same but they are also designed to achieve a similar desired output.
https://genesisloudspeakers.com/

And in contrast my 0.75w/ch SET amp driving a single driver set of HP's can reach to near 10Hz and at a fraction of the cost of the Audio Artistry Beethoven speaker system, let alone the cost of the Genesis speaker systems (up to the $300K+ range).

And yes TRUE Trouser Flapping (TTF) where the the pants actually do flap in the 'breeze' and can be observed moving, does embody bragging rights unto itself, but at a cost above and beyond the audio system itself.
Like loosening the ceiling rafters (with the accompanying falling dust), the window and door frames (they make more and more noise as they continue to loosen), the floor joists and subsequently the flooring itself will loosen and act as a drum head, along with the whole rest of the house, not to mention the houses in the nearby vicinity.

Of course if you can afford an audio system with 6-7-8 digits of dollars, perhaps the neighbors are so far away from your stone castle that the above concerns are but a moot point. hahahahahahahahahahaha

Still the contrast of being able to rattle my teeth and internal organs with under 1 watt, and NOT have the police show up asking me to turn it down because, blocks away, dishes and collectable ceramic nic-naks are falling to the floor, is a definite plus in my book…
hahahahahahahahahahahahahahaha
