I now have found the perfect frequency curve for my speakers and room. I lose 10 dB of gain by running the Convolution filter in ROON but my preamp (HPA4) has a 10 dB boost feature. ROON also has PROCEDURAL EQ which allows you to reclaim that lost gain. I decided to use my premps boost instead (I could use both).
Remember, my posts about the AHB2 not hitting hard enough. Well with the drivers and the wiring fixed. With the gain boosted and mainly with the Convolution filter. Things are really rocking. A big speaker in a small room sounding like it is now is incredible. No fatigue at all.
I also spoke with Benchmark technical support because my preamp had a glitch on the boost adjustment (we fixed with a factory reset of the GUI). They also said that 2 mono AHB2 can put out 700 watt at 2 Ohm. They cannot publish this because the amps cannot run like that for extended time. They also said the mono amp is stable to 1 Ohm. It also has the forward correction to stop clipping to get to the speakers. Just an FYI.
Wow, just so happy with what I am hearing today. The CS3.7 has never sounded this good in any dealer demo I went to with much more expensive gear.
