There are some others that could have been in on this . . . but this was certainly extremely helpful, and I have to wait and see how production units of Dave Wheeler/Eric Heiserman's collaboration turn out! True but since the main goal was to give Dave a solid benchmark, I think mission accomplished! PS, I still can't believe she's mine

Listening to Black Sabbath - Mob Rules. Holds up. First LP I bought with my own money. No idea why! I still listen to Heaven and Hell as well as Mob Rules once a week or so. The first few seconds of Neon Knights kills me. Every single time. The drums are amazing, doubled kick on the 1's. Guitar tones slay. Geezer being the bass guitar boss he is and Ronnie...such an upgrade from the previous singer. We saw them at the Chicago Amphitheater during the Mob Rules tour. I still remember tiny bits of it. I mostly remember smoking hash in my buddy's '67 Camaro on the way down to the show LOL

RIP Martin Birch. He literally recorded the soundtrack to my musical youth. Such an incredible musical resume. I wonder if donr would be so kind to enlighten us with what it was like to work with Martin?

I’ll delete it . I thought Dan made one All good man! We sell the same SMPS. He has his own filter though.

If I’m not mistaken the smps is made by Danderloo. Sold by Jeff This is not accurate. I'm 99.9% sure they come from the same place in China as do the Radial and API SMPS.

Thanks for your suggestions everyone. Today I hung two heavy blankets from the curtain rod in the deadest corner of the biggest room and backed the mic up against that, similar to the diagram Doug posted. Sounds totally decent! Turns out I just needed to put my dunce cap on and sit on a stool facing the corner. I see a Mogaine!! \m/

CAPI VP28 is like a Vintage API and a Vintage Neve in one... Super fast, punchy and open but larger then life and smooth like a Neve. It's my desert Island pre-amp I would absolutely sell everything and have a console of these. John And sadly, out of stock every time I go to order . . . a great complaint to have if you're Jeff jsteiger ! Tryin to keep stuff in stock during this pandemic has been a chore. Supply chains have been tricky and our demand is way up. Saying I'm blessed is an understatement. We should have another batch of inputs in before the end of this coming week.

Just to complicate everyone's opamp world a little further...I am pretty close to done with my take on the 70's ADM202. Its a 10 transistor discrete amp. The original used the LM394H super matched input pair. I am using the AS194H remakes which are stellar. The original used TO39 metal can outputs 2N3053/2N4037 which we also have. The amps are fantastic and have their own unique goodness different from any of the others I have heard. They will of course be in the 2520 style footprint. I was originally gonna use BC550/BC560 for the interstage transistors but switched to BC327/BC337 when the BC560 went out of print. For shits and giggles, yesterday Joel and I compare one using the same NOS 2N5087/TIS97 that we use in the CA-0252 and holly molly it got easily 8% better so that is our final ingredient.

I've been buying my PCB's from South Korea for many years now. They are hands down the best I have ever seen including US board houses which likely sub to China anyways.

My friend Derek Drye tracked his and his wife's vocals for this song thru a Heiserman H47 Tube into a Heider FD312. Wait...you’re not going to Rickroll us with that, are you? I feel like I should know what this means but...I'm drawing a blank. LOL

My wife just read an article from Feb 7th 2020 that 40 out of the 50 states have enacted economic nexus laws.

There are many variables on collecting the sales tax Nexus. Each involved state has a dollar threshold as well as a # of transactions threshold. We have been tracking these since the beginning of last year. Thankfully we will likely and hopefully never hit the threshold for any state outside of TN. Big sellers like Reverb and eBay are of course way over these thresholds. California was the only state we were getting close on and they since raised the threshold to $500k which will never happen for us.
The burden of filing for status in each of the states and filing multiple sales tax returns is a MAJOR PITA.

I don't think the crossover at 120 has anything to do with it. It's probably just room dimensions more than anything. I've worked out of 5 different rooms over the past 10-12 years. All home type rooms of various sizes, with several different sets of monitors, Pro Ac's, Focal's, Amphions, Subs, no Subs, etc...all of them have had significant issues in the 60-120 or so range. This is with a lot of treatment. I do think that separate subs are more flexible in these kind of spaces than 3 way full range monitors, although they have their own issues to work out. I also bought a Trinnov a few years ago, and that made a huge difference. I have been talking with Jeff Hedbeck and considering hiring him to help with my room. I hope there is improvement. Jeff is the man! He's the blue collar acoustician. I know folks like dandeurloo and drbill will agree!

Measurements I took on LC53A for +/-10 @ 15kHz are about 1kHz off from each other. Slightly further apart on the TB550A. The cuts are higher in freq. Neither peak at 15K, both are 13K8. 88K2 measurement bandwidth. Yes exactly. When I did the LC53A I matched the actual center frequencies of a 550A, not just what is printed on the faceplate. As for the 550A, the math for the 15kHz filter is dead on but in reality...13k8. The gyrator graphics are more perfect reciprocals. Paul also told me that the proportional Q of the GME20/550 was simply a byproduct of the need to adjust the Q resistor to keep the frequency centered at the different cut/boost amounts. This is also why a mastering version is not a simple task.

You cannot correct it. Nothing works unless cut and boost filters are different especially at the high end. I have talked to Paul about this too. Its just how it is.
You also cannot simply change 6 resistors and have a mastering version.
Paul also told me a funny story about the 550A-1. After they shipped their first batch to Sunset Sound, they got complaints that the Q's were way different than the originals. Paul did some sweeps and found they were not proportional Q like the originals. He brought it to Saul who did a 'hand to the forehead' and said they only compared at +/-12 and not the rest of the cut/boost amounts. They had no idea it was constant Q until it was too late.

Not exactly. The bridged-T notch filter that Melcor/API use is pretty accurate (as far as cut/boost frequency) up to 1kHz but starts to shift as you go upwards beyond there. Cut/boost center frequencies run off significantly by the time you get to 20kHz. Just the nature of the beast. I'm not sure that we're talking about the same thing. The same two caps and the same resistors to form the bridged T are used in cut and boost, just moved around. Whatever that center frequency is the same amount of boost and cut for that frequency is applied, and is reversible. There's some very HF rolloff due to caps used for stability around the buffers/amps, but we're talking <1 dB and that's there even when set flat. API manual notes the same thing. "When switching an API EQ from boost to cut, the exact same components are used, reorganized around the amplifier for the appropriate function. This guarantees 100% reciprocity. The benefit becomes apparent when a track is re-equalized to remove the previously applied equalization. The engineer can be confident that, because of the fully reciprocal design, a truly flat frequency response will be restored." Thinking about it more, I suppose due to the difference in the source and load impedance presented to the filter between the feedback loop and the buffer there will be some variance between the two positions, but this should be less than a dB. Try running some +12/-12 sweeps set to the same frequency and you will see. I am specifically talking about the 550 style EQ's. For example, with a 550B the 20k cut/boost are WAY different. The center frequency shifts dramatically.

They can be great. Try them one some acoustic guitar. Maybe not bluegrass cross picking but I like them on strummy rhythm. I just wish they weren’t so damn expensive. Jeff, make a kit version!!! jsteiger I know the VCR2N FET that was used is unobtainium. Not sure its a road I wanna go down...I have no idea what they are using these days. Maybe they have a plethora of NOS parts.

Hairball has been doing this a LOOONNGGG time, as long as CAPI, or pretty close. Millions served. Mike started Hairball about 2 months before I opened the CAPI store. He was near the end of 2008 and I was the first of 2009. He's a great guy and only sells top shelf stuff.

I always wanted a real 560.... cheers Wiz Not sure I’d want the real thing because there’s no recall with the sliders...but jsteiger ’s LC25 and 40 -“are somewhat based off of it and the bomb.

I too have caught the CAPI bug. I've been stacking up on the VP25's. I have been thinking about the missing link.Jeff is truly the man. Yes you've been going at it lately!! And I appreciate you for it.
