Ron’s New System

I am trying to use the same position and technique and SPL each time. I'm playing the break-in CD basically all day and all evening long except when I go to sleep (only because I just can't relax with super high power tubes on while I'm sleeping). So this measurement is about 50 or 60 hours after the last one I posted.

It is difficult to discern if the break-in is smoothing things out a bit . . .

Can't you borrow an SS amp for the (heavy) burn-in of the speakers and use the tube amps only for serious listening?

 

[Ron Resnick]

Work on reducing the rise at 3-6 KHz…probably where the brightness is coming from.

Good work, Sherlock!

Way too much aggravation. I think it's no big deal for the system to not be burning in for the few hours I'm sleeping. And I want to hear and begin to understand the system with my amps.

Ron - have you ever paid any attention to the Harmon curve? Just curious.

Ron,

If you want to measure the action of room treatments you should not measure frequency response but the decay curve or waterfall - amplitude versus time versus frequency. See https://gikacoustics.net/understanding-decay-times/

Yes, subjectively I like the Harman Curve. I would be very happy with that frequency response:






But what you posted looks like a nightmare to my ears. This doesn't look anything like that curve.

Isn't the Harman curve an headphone affair? Harman created a target response for speakers - the total sound power curve, that is created by weighting the angular frequency responses of a speaker and shows a decreasing response versus frequency.

This system definitely is the most resolving I ever have had.

I think the woofer tower, with its 1,000 watt Class AB Gryphon amplifier, is a brilliant design. It feels like the woofer towers just take control of the room.

Are you getting a reference turntable soon Ron ? The Denon, nice as it is, is not on the same level as the rest of your equipment at this point !

I thought Ron bought the AS-2000. He just needs DDK to set it up.

No Tube Traps; this is 4' x 8' x 2" absorption panels in the corners on the front wall:

Dear Ron,

Here’s link to the U.S. dealer for the Swedish made Helmholtz resonators with ajustable ports.. Hope it might be of some help.

Yes, this firm builds listening rooms using SMT (Matt's) products.

Yea, this firm builds listening rooms using SMT (Matt's) products.

Yes sir, they certainly do. As you saw on the pics I have used the bass resonators myself, and they do amazing things in troubled rooms. As I had the opposite frequency trouble in the bass region that you have, I used the VR-6 for my bass node at 30-32Hz, and the two VR-4 in each corner for the bass node at 65Hz, which in turn also adjusted the troubled dip at around 100-105 Hz due to the overtune indused by the 65Hz frequency.

So they are certainly something to concider.

A giant THANK YOU to our dear friend, Rune Skov, Sales Director of Gryphon Audio Designs, who flew across the planet to visit Tinka and me today, and to listen to and position the Pendragons! Rune was accompanied by Anthony Chiarella, CEO of Gryphon North America, and by Joe Cali of Joseph Cali Systems Design.

It was wonderful to meet Anthony, a planar loudspeaker kindred spirit, and to talk with and to listen to music with Anthony and Joe!

Joe is the Gryphon dealer on the West Coast, and embraces an all-Gryphon system building philosophy to reproduce music the way the artist intended.

You are welcome to visit me and to examine the incredible craftsmanship and design and sound of Gryphon Audio Designs loudspeakers! And if you're interested in a Gryphon system, please call Joe!

Did they improve the sound of your system Ron ? Or just tell you that you need more Gryphon gear ?

 

[gleeds]

If ever there was a safe bet it is that Ron will remain a tube amplification man for many, many years to come

The room is looking great Ron and it must have been fun to have your friends from Gryphon come and help calibrate the Pendragon set-up.
