Do YOU have a flat frequency response in your room?

@mikelavigne , I agree that is a better question, asking if you have the frequency response that you want. To get that answer though you would have to measure it and compare it to a flat response to determine which is preferred. Some speakers are designed to take out the harshness around 2 to 4hz and build in a "gundry dip".

Marantz has a target curve within Audyssey, there is a "Harman" curve as well, good point. Let me rephrase and say that until you know what your desired FR curve is and have achieved it, spending money on new gear is rather frivolous. You still need to measure the FR and dial it in before new purchases to avoid the dangers of an audio money pit. However, you can’t really be too far off base with simply a flat curve to get started.

@erik_squires , I have done some research, here is a good foundation. Even if you don’t agree that flat is your preference, you need to get your preferred response before buying new components. Imagine not liking your speakers, buying new ones, and then finding out the real issue wasn’t the speakers but the FR of getting the speakers dialed into the room.

From "The Measurement and Calibration of Sound Reproducing Systems-1. Introduction"

Flat on-axis frequency response is clearly the engineering objective for most of these systems. Those that deviate significantly earn lower ratings in double-blind subjective evaluations. Although there is more to be considered, a flat direct sound delivered to listeners is the basis for most reproduced sound.

@erik_squires , I checked out your virtual system and we both use Mogami cables, Isoacoustic stands, and maple platforms. We also took care to treat the room and the ceiling, nice. If you are using ARC can you post the before and after of your FR in your system profile? If not, NP. It would simply be interesting to discuss.How were you able to dial in the placement of your speakers, are they higher than ear level on those stands?

@mikelavigne , you obviously have dialed in your room meticulously, did you use any dsp? I noted in another thread that we are both using Auralex diffusors. You are using the T-fusors on I think the first reflection point? I’m using the Gefusors backfilled with polyfil for some absorption on the ceiling above the MLP and on the ceiling in the rear corners of the room.

Not posting curves, but I designed my speakers to follow the Bruel & Kjaer recommended room curves.  Yes, as Troels Graveson has written, sometimes when you make a speaker you end up finding the ideal listening position is not the ideal measurement position.  In the case of the SNR-1 they just  sound much better on the m id-woofer axis.

@erik_squires , great example of how you dialed in the FR you wanted before chasing gear to get better SQ. Did you use the mic that came with your receiver for your measurements or something else?
