No recording of an acoustic instrument is 100% equal to the original, regardless of the medium used. The question that many audiophiles wrestle with is how it sounds vs how it measures, with those who listen to music preferring the former concept vs those who listen to their gear preferring the...

With all due respect to your experience, my 1960s experience with LPs was quite different. I learned to play electric bass by playing the same passages over and over. This would not have been possible if the frequency response was weak below 100 Hz and with decent extension to at least 40 Hz...

I find your statement that records (LPs) don't reproduce below 100 Hz a bit errant. Low E on a regular guitar is 82.41 Hz, and on a bass guitar, half of that. No issue with either of those frequencies on my LPs from the 60s and 70s. And if you claim it's due to RIAA EQ, that's irrelevant...

My techno breakthrough was discovering that the resident DAC within CD players could be improved upon, which led to CD ripping to FLAC files on a NAS. Then a few iterations of accessing NAS files with NUCs into better DACs, and I now rarely spin an LP to get "better sound". The ease of access...

The amateur radio industry has been using oil filled dummy loads for years. They're 50 ohm impedance (but quite possibly that's also the resistive spec). See Heath Cantenna. It may be adaptable to audio power measurement. I have a few amps that can exceed my Tenma 100 watt stereo dummy load...

Mike, that is good to know. Until I started measuring, I was convinced this was the best listening room I've ever had. And it still is, but it is amazing what small moves in speaker placement can do. Unfortunately, the null has so far been immune from placement.

Mike-48, Thanks for the thoughts. The null valley spans about 10 Hz peak to peak, which is a lot to lose in that Hz range. I'm really surprised I don't hear it with as much absence as the graph indicates. Probably should try the same mic / interface setup in another room to ensure it's not...

Mike-48, appreciate your thoughts. I don't have issues with slap echo thanks to the area rug and the acoustic ceiling tiles. I have played bass guitar for many years, and am typically critical of systems that don't provide well defined bass. Oddly enough, with 42-43Hz falling in the lower end...

Sonnie, I appreciate your input. All measurements were taken at the listening position. The equipment wall is one of the "monuments" that can't be changed, nor can I block off the smaller portion of the room in an effective way. There is a TV in the middle of the wall over the equipment rack...

Hoping to get feedback from the voices of experience in the group. Room dimensions are attached. It is a basement room with vinyl over concrete. There is a 9' high drop ceiling with good quality 2 x 2 acoustic tiles, a sofa at the X listening position, a love seat along the wall with the dog...
