For those interested in the new SO and don't mind tinkering a bit, you
can see what filters the new SO is coming up with - but it's a bit of a faff to get to.
Konfig creates a log of everything you do - and in that log is a copy of the current SO profile which it downloads from your DS. On a PC this is in
c:\<{username}>\AppData\Roaming\Linn\Konfig\UserLog.txt
What you need to do is to
- Close Konfig and apply your SO v2.0 from the web interface (if it's not already applied).
Open Konfig, wait for it to discover your DS, then close it again.
Open the UserLog.txt file
Delete all of the text up to (but not including) <Optimisation
Delete all of the text that comes after </Optimisation>
Save the file on your desktop as an XML file, so MyNewSO.xml for instance.
Open the XML file in a browser and you'll see the new filters it's come up with. Unfortunately it's not really possible to create an old SO profile that replicates the new as the left and right channels are radically different (at least in my case). Previously the frequency and bandwidth of each mode filter were identical between left and right speakers, now it seems they can be different (which makes sense).
Now - the new SO takes MUCH shallower cuts (but typically over a much wider bandwidth) than the old for my setup. Here's the calculated values for my system using the old SO:
Left Speaker:
Mode 1: 44.68 Hz, -34.6, 0.120416
Mode 2: 59.84 Hz, -13.63, 0.089918
Mode 3: 75.90 Hz, 0
Mode 4: 79.61 Hz, -28.85, 0.067587
Right Speaker:
Mode 1: 44.68 Hz, -33.75, 0.120416
Mode 2: 59.84 Hz, 0
Mode 3: 75.90 Hz, -12.56, 0.70887
Mode 4: 79.61 Hz, -18.62, 0.067587
For SO v2 (with a more accurate room layout admittedly) I get:
Left Speaker:
Mode 1: 43.457 Hz, -19.177, 0.448749
Mode 2: 51.270 Hz, -7.646, 0.188036
Mode 3: 82.030 Hz, -12.751, 0.370522
Right Speaker:
Mode 1: 43.457 Hz, -7.184, 0.229523
Mode 2: 50.780 Hz, -13.192, 1.656257
Mode 3: 61.035 Hz, -0.4, 0.105267
Make of that what you will! Interestingly the basic format of the Optimisation profile is more-or-less the same. There is still provision for four custom filters and there are still 'Adjusted' versions of each of the calculated filters - so there is still some (slight!) hope that at some point Linn will re-introduce the capability to fine tune.
Edit - the bandwidths in the XML file are in Q values - you need to convert them back into Octaves for them to make sense compared with what you see in Konfig.
