Long update:
Played around with the Parasound NC 200Pre unit a bit.
Added sub, integrated AVR using HT bypass, and a bit of placement/positioning.
Settled into the AV-Rack (lower row, center cubby hole)
TV/Movies
This position is calibrated as a 3.1 for movies using Marantz's Audessey.
L/R/C are all set to large and are carrying signal 40Hz and above. Sub is fed with LFE set to roll-off at 120 (I think).
Depending on the movie content, I just tweak the channel levels using AVR remote, if necessary.
The NC200Pre is usually in standby mode for TV/Movies. HT bypass is the default in standby.
It just passes whatever is on L/R/Sub input to output.
All family members agreed it is good enough for TV sound.
2-Ch/Music
For music listening, I have found that my ears/room prefer the L/R/Sub pulled into the room.
Front baffle of L/R is 40" from wall behind it (27" inches from rear port). L/R are about 80" apart (tweeter to tweeter).
Main speakers can practically go down to 55Hz in my listening space (my guess).
Sub is pulled in approximately to line up with front baffle plane.
I am currently using the 80Hz (and below) output from preamp, not the full range summed L+R.
Also, high pass filter to L/R on preamp is turned off; they get full range.
The sub is a sealed one, with 8" dual drive and 100W of class A/B amplification.
The positioning of sub is such that the drivers are perpendicular to L/R driver plane.
The sub is a 20-year old unit that can realistically go down to 40Hz. I have nicknamed it "20-40".
Listening Position perspective
This is primarily for music listening.
- The coveted recliner is about 8 ft from speaker plane
- When L/R are facing straight up (no toe-in) the staging is wide and great for background listening
- When L/R are toed in to sweet spot, the imaging is tighter; separation of instruments is wonderful
- DAC which is primarily in OPT mode due to streaming via Chromecast Audio is warm and fatigue free
- USB input via laptop is recommended for full album listening
- Bass is
'taut'; mids/vocals are
'fluid' and highs are
'airy' (using typical audiophile adjectives)
Sub usage and impressions
Sub is dialed in at 50% output and the internal LPF is set to max (effectively off).
I'm relying on the preamp LPF to send 80Hz and below to sub.
Bass/Treble controls are +/- 8 points each; I have not had to use them in the short time I've listened to the rig.
The preamp has a sub on/off control on remote; when "on" it can control the sub level +/- 16 points.
Parasound has done us all a great service by providing remote control of these functions.
On any track, depending on mood, one can engage sub or not.
When engaged, can quickly fine tune the sub level per track using the remote.
On most tracks with a good "beat" the sub brings in a fullness/richness to the presentation.
It does not overwhelm the overall presentation. There is no boom/muddiness or lag.
In fact vocal rich tracks also sound a bit more engaging. Makes me want to sing along (which I do quite often anyway
)
This has given me further confidence to seriously explore a REL (or two).
Here is the place where I have to appreciate Onkyo for engineering a good musical sub 20 years ago.
For sub in 2-Ch "fence sitters" (I was one until now), please try it out with the proper gear.
It is a wonderful and enriching experience.
Cheers,
