brotw: " I believe room correction has the benefit of improving the tonality of the rooms bass response at the LP. Of all the speakers and amps that have made their way through my listening room, not one did not benefit from dsp. Music sounded more coherent and live with tighter bass and imaging every time I flipped on the Dirac filter. The mixed phase filters are great, and perhaps they are correcting the speaker crossovers and room all in one. "
Hello brotw,
I think it’s best that I just accept your claim as fact that room correction/DSP/Dirac have had positive effects on your systems. I also realize individuals are unlikely to improve their system’s performance without having the sense to learn from the experiences of others and taking the initiative to actually audition the promising suggestions in their own systems.
However, I’m a bit confused about exactly what component you’ve been utilizing in your systems that contains DSP/Dirac filtering capability, can you let us know?
My prior preamp was the Parasound Halo P5 with bass management, so I am very familiar with that unit. Imho, it’s a good preamp with a very neutral sonic signature. I now use a Levinson 326S preamp in my system. I didn’t see a purpose in having 3 bass management systems, one with controls on the back of the P5, one incorporated into my Oppo 205 Bluray/CD/SACD player and the one with controls on the front of my AK Debra 4-sub amp/control unit. I also liked the improved tonal quality and more 3 dimensional sound stage I perceived with the 326S in my system.
However, I think the P5’s bass managent could prove very useful in your system, especially if used to reduce the bass duties of your Line Magnetic 508ia SET tube class A 48w/ch integrated amp.
I believe your best solution is utilizing a pair of good quality self-amplified subs in your room. You could connect both subs to your P5, set the P5’s bass management controls so that all bass frequencies below about 60 Hz are sent to the subs and all frequencies at or above about 60 Hz are sent to your 508ia. I think this would likely eliminate your 3-5db suckout near 50 Hz and improve the midrange, treble and stereo imaging performance of your 508ia and main speakers combination.
You could then optimize the overall system performance and balance by making small adjustments to the low and high pass crossover frequency control settings on the P5 by ear and preferences.
For best results, I recommend precisely locating each sub in your room, and in relation to your LP, sequentially utilizing the ’sub crawl method’. You can google it for details.
