Great to hear you find the single AHB2 so good with the 3.7s. So do I. Also, I don't know anything about Convolution filters, but my interest is tweaked here.
Gotta ask, how did you notice that boost adjustment glitch in the preamp? I have the LA4 -- essentially same as HPA4.

@tmsrdg I know you had a single AHB2 and are also a musician. I was thinking why does my system sound bad and yours so good with a single AHB2. There were hardware issues for sure but the room was still a big impediment for me.

Here is a link to a post I made that digs deep into what I did.

Here is a another post I made that has a bit more info.

The ComputerAudiophile.com site is were this advanced DSP stuff gets chewed around more than here on A’gon.

All I have to say is this Convolution engine in ROON is brilliant stuff. Just transformed my system. If you want to see some graphs send me PM and we can do that by email. Don’t tell anyone since email is not allowed.

@tmsrdg Oops, forgot to answer the question about the boost adjustment. My HPA4 had the boost disabled on XLR1. XLR2, RCA3, and RCA4 all worked. I worked it out with Benchmark tech support. We ended up doing the FACTORY RESET on the GUI. I lost some settings but not big deal to manually restore them. I think I may have seen this before.

It was important to get the 10 dB boost today because the Convolution adjustment took away 11 dB. I learned a about ROON DSP settings the past few days. There is boost in the ROON settings too but as of now I have disabled that.

Thank You for the update. There are many here that enjoy Music servers and streaming via ROON. Good to read that your speakers are settling into your room/space.

Happy Listening!

@ yyzsantabarbara ,
Thanks for the responses and all the links. My Aurender N10 server is incompatible with Roon, so I can't consider the Convolution app.If there's one thing I'd like more of in my system, it's low frequency "weight."  It's pretty easy to tell when listening to say, solo piano music, where the low end drops off a bit.  The listening room is adjacent to another equally sized room separated by sliding glass doors (open midcentury modern floor plan). My wife's Steinway is literally only 8 feet to the right of the right speaker on the other side of the doors. She can play the same passage that we've just heard from a recording as a reference. Everything tracks exceedingly well, but, yes, lower octaves don't have that same impact. I have seen the future, and it involves subwoofers.
