Nice Sound System for Home

I can't get anything custom made because the real one yet to be made with all my designed filters will be in a U5 size enclosure, this bare bones prototype is only a U2 frame.

:challengefailed:

God damn it.

So get started on the enclosure now while you're waiting.

Trust I've thought long and hard about the master console unit for the past couple years. I've been leaning toward local madrone veneer over the same condensed layer dampened baltic birch plywood base of my turntable. There won't be any stray motor vibrations to cancel but it'll never warp over time that way.

Also I've learned easy access to the back is key to change connections, phono resistors, and tubes even if the NOS one used in the first stage gain should last over 10,000 hours of use.

You'll think I'm crazy but I've been looking into a horn that's three feet longer and almost two feet wider than the mammoth I have now.

Also I'm VERY pleased to learn the EQ I'll be using has discrete 0.5 dB increments unlike the 1 dB I thought it was going to have which would've been too crude for the sensitivity of my system.
 
My neighbors across the street about fifty yards away sit on their porch and listen to my system even with all my windows closed!
 
I've just finished a book on Phil Spector - I'm itching to hear some of the mono stuff up loud. You got a spare room there? And got rid of those rats yet?
 
Rats been gone a week after poison trapping attic. My living and dining room will be converted to a mini-theater live mastering studio. I have a disc by the contralto Clara Butt performing "Rock Of Ages" (E condition) electrically recorded inside a large church with a wall size organ. When I play it feels like I'm inside an equally large chamber with vibration coming through the ground. I'm curious how different it would feel if/when I suspend the speaker.

I feel like I should be giving 'concerts' at Lincoln Center although ideally acoustically I'd still want a space at least half the width of a traditional auditorium to maintain true one speaker mono clarity. I had some special chocolates at my friend's house tonight so I'm feeling extra depressed about this, the lost arts that exist mostly in non-public public and private dark archives. Of course hearing Chaliapin in holographic fashion would shame any living basso today as would any number of long forgotten artists.
 
Can't find my socket wrench to get a jammed nut off my open baffle to install a cheap driver to test my system before I try on my reference driver, ugh.

Just to preserve this for posterity.
 
Well found the socket, running S.E.T. to S.E.T. is whole different ball game of sound and makes my cheap drivers sound like shit but I'm chalking it up to like putting a ferrari engine in a prius.

Waiting to hear from my engineer how much it'll cost me if I blow my main driver. :popcorn:
 
Well I hooked it up.

Unfuckingbelievable really.

Uber-holography, feels like sci-fi but from 100 year old discs.

I can only turn the volume control up three quarters before a soprano shatters my window.

Totally spooked, never been afraid of a sound system before.

Jesus Christ.
 
Looks simple and deceiving, also the plain box is just the prototype and mine will be three times bigger. My tube regulated tube power supply's not shown either:

The extension cord in the upper left is just for the LED strobe switch to my turntable, although I do need to upgrade my power strip.

Strangest thing ever happened to me. As advised by my tonearm/sut engineer I plugged the arm directly into my pre bypassing the sut. The cartridge works perfectly! But and this is the most mind-boggling but I've ever experienced in audio, this vintage cart with a specified output of only 0.5 mV is just as loud as my contemporary mc cart with a 1.5 mV output ! This has to be impossible !!

I'm waiting to hear back from my engineer.

Mind blown.

I have no idea what much of that actually means, but I'm happy to hear that things appear to be working.
 
It means those levels being equal should be physically impossible.

You have gain coming from somewhere, most likely static.
 
Engineer says internal resistance of coils also affects gain. I've never understood the two different impedance values for carts, internally and what's connected downstream.

There's some distortion from the vintage Ortofon, not sure if due to failing stylus suspension or misaligned azimuth or both.

I ordered a 100 pack of micro brush eyeliner applicators for stylus cleaning. Regular Q-tips are too crude, dunno why I didn't consider alternative before.

Unfortunately these things operate at such tiny voltages and the step up is so significant that at cat hair can do it. Cable length, or try swapping it?

Why do you mean about the impedance comment? You mean for example how a coax cable downstream is 75 ohm?
 
Here's my contemporary Ortofon cart:

Ortofon - Mono CG 65 DI MkII

You can see the two impedance specs.

My vintage Ortofon cart is over 50 years old and looks unrefurbished so I might need to send it to England or Germany to get it back up to spec. Ortofon unfortunately doesn't provide support or work on pre-C type carts.
 
My brand new Pultec EQ isn't surgical enough to notch filter record wear noise without diminishing too much of the music so now I have to custom order one from Sweden that's considered the very best ever made for remastering.

Anyone wanna buy my $4k Pultec? Learning curve so brutal. :dumb:

What does this mean?

I need cutting edge post 2000 technology and I fell for the Pultec name the way some fall for Rubinacci suits just by legendary name and good interface. My needs are very specific and I can't buy one fucking thing off the shelf.

Stay away. Not for you, for Audiogon.

Audiogon, along with 99.99% audiophiles, never focus on correcting the source, which is kinda strange to me. Gearslutz is the mastering forum.
 
I'll have two meters on my console, one for first gain bias and the other for power supply voltage.

If I get a power supply for my turntables I'll have four meters! NEED TO BINGO FOR METER.

Verrryhappy hermit EQ engineer in Swiss Alps is making me mono monster EQ. BESPOKE
 
Told Swiss guy I'd order tomorrow but now waffling on this Danish EQ with serious tube action:

How much are these things costing you Leland? Can we get a price breakdown on the various parts?
 
Too much and no thanks. Paying my monthly credit card bill's painful enough.
 
Fuck me just found out the Danish dude retired, couldn't sell enough units with the dollar being so weak past decade.
