I ran REW yesterday on my stereo system, not the A/V system I listed in my profile. My stereo consists of the following equipment: YS-Audio Audio Experience Balanced A2 preamplifier; ICEpower 1200AS1 & Tube Fantasy 300b PSET monoblocks; Von Schweikert VR-4 Gen III HSE speakers; Topping DX7 Pro DAC; Volumio on Raspberry Pi4; Pro-Ject Phono Box RS phono preamp; Opera Consonance LP-2.0 turntable; Mørch UP-4 tonearm and a Grado Sonata 2 cartridge. The ICEpower amp is on the woofer module of my speakers and the 17W PSET is on the tweeter midrange module. I use a Yisheng HiFi Relay Volume Control on the ICEpower amps to balance them with the PSET amps.
My room is odd shaped and untreated. My amps sit between my speakers:
Just to the right sits my LP storage (IKEA Expedit) and preamp:
This image shows the relation of the Expedit to my speakers (covered with boxes when not in use):
This is the layout of the room:
There is a Kurzweil Mark 150 digital baby grand piano on the angled wall. The wall behind my chair is kneewall that is just slightly higher than the chair. The opening next to my chair is into a good sized living room and the open doorway on the left is the kitchen.
Here is a psychoacoustic smoothed plot of my first set of measurements taken from my listening position (L+R .mdat attached):
Red is R, green is L and blue is L+R.
I have six 2' x 4' 2" rockwool acoustic panels that I used without measurement in a prior home that I can use in this room. I'd like to reduce the suckout at 110Hz and hopefully address the entire range between 65 and 450Hz.
The Von Schweikert crossovers are acoustic fourth order at 150Hz and 1600Hz.
My question is that now that I have my first set of measurements, what is my next step?
Thanks,
Martin
