While playing with my new Puffin DSP phono preamp, I am trying the built in Room Eq function. The manual advises using an RTA app on your phone to determine the room mode usually around 300hz. Sure enough, I checked using the RTA app and saw a peak bang on 300hz. So, I have engaged this feature on the Puffin. This got me thinking about the DSP features of Roon. Being the usual minimalist audiophile, I had not paid much attention, but now I am having a rethink? Right now, I have engaged a Parametric EQ notch of -6db centered at 300hz with a Q of 2.6 to mimic the Puffin default setting.
So, my question to those that use Roon, do you use the DSP and have you tried the 300hz room mode eq?
Based on my reading, this is at least one thing every audiophile should try in their system.
My Martin Logans have a mid-bass control that offers a +2,0,-2 setting centered at 250hz. I believe this is a nod to the Schroeder Frequency. I set mine to -2 before I knew about all this and adjusted the 75hz control to -3db. I arrived at this intuitively and it eliminates any boominess I might have had.
The beauty is that Roon incorporates the ability to adjust this very precisely with PEQ filters. It's a freebie that adds value to Roon.
Generally, I am a purist audiophile but I am open to experimentation when backed up by at least common sense or actual scientific study. I do believe with computing power now practically free it makes DSP a no brainer. I think one of the big trends going forward in speakers will be self powered dsp controlled. It makes so much sense and I think the ultimate audio quality will prove this.
I once asked the proprietor of Janszen audio if he preferred powered speakers from a design perspective and is answer was a definitive YES!
