Update - Used an Audio Spectrum Analyzer App, and...
...changed out the Creative Labs Sound Blaster X-Fi Go! for an Audioquest Dragonfly v1.2. Wow! What a difference! Of course, adding the new sub helped as well. (http://www.e90post.com/forums/showthread.php?t=1071029 )
I now have almost everything set to FLAT...treble, bass, and most EQ settings, with the 200hz up 2 bars and the 100hz and 500hz down one as per the spectrum analyzer app. With the sub equalized (via an Audiocontrol EQL), I now have a pretty flat response (from 31.5- 16k) on the spectrum analyzer (https://itunes.apple.com/us/app/spec...490078884?mt=8 ) and... ...the Logic 7 system sounds better than I ever thought it could. The previous "smiley face" EQ curve was purely to make up for the loss of the low end before the addition of the sub, improved DAC and proper spectrum analysis. Of course, the highs had to be boosted to compensate for the overuse of the low end EQ bands before the sub was added. So...the poster who said a flat Logic 7 system sounded horrible was right IF you are dealing with an unprocessed/improperly processed audio signal. Add a (good) DAC and watch what happens (with the best way to accomplish this being the use of the AirEnabler, IMO (http://www.e90post.com/forums/showthread.php?t=971083). Money well-spent! Bottom line: You ultimately do what sounds good to you, but...it can take a long time to get there if you don't have a good, clean signal and some solid guidance (e.g. a spectrum analyzer).

Update 2 - Fiio E-17
Turns out the Dragonfly couldn't handle the volume output of the AirEnabler required to have the AUX input level be anywhere near the other sources (CD, SAT, FM). I could not get it to take more than 70% from the AirEnabler without obvious distortion.
So, I reinstalled the Fiio E17, which I thought initially was defective due to some crackling but realized that it, too, couldn't handle the 95% volume output level I had set in the AirEnabler (with default setting being 60%). So...I dropped the volume of the AirEnabler down to 85% and bumped up the volume of the Fiio to 58/60...perfect! No distortion and all source levels much closer to being matched. And...the Fiio sounds MUCH better than the Sound Blaster (I originally used) and the Dragonfly...better clarity, soundstage/separation, and detail, especially once I reloaded all CD's into iTunes using Apple Lossless encoding. But, the point of this post is: With the Fiio and the BavSound Stage One Speaker Upgrade (which is great!), I redid the Spectrum Analyzation...three times on three different days...using an external mic (iPhone as source, iPad mini with mic as monitor) and got a VERY different equalization pattern, something I would not have guessed (see below). And every genre of music I listen to (from classical to jazz to heavy rock) sounds good and accurate, with only sub adjustments being required (using LPL44 external sub control with my PG xs2500 amp). Also, the Fiio has BALANCE controls so I was able to adjust the balance to center without using the L7 balance, the latter tending to ruin the soundstage. The Fiio balance adjustment (+4 to Right) was perfect and the soundstage is great. So...here are my EQ settings with this setup (AirEnabler, Fiio E17, BavSound Staqe One, stock L7 amp and rear speakers and underseat woofers), using AUX input and THEATER Surround setting, not Concert. Although the 200hz adjustment seemed weird to me at first, it now makes sense knowing we have 4" mids and 8" woofers as stock sizes in the L7 system.

But, these settings were made through the Logic 7 system after installing the BavSound Stage One speaker upgrade. The ones before the speaker upgrade were pretty similar, however.

Anybody ever compare sound quality of the AirEnabler / Fiio E17 setup to an HRT iStreamer setup?

Just had a CCC upgrade to CIC and have lost theatre and concert hall options just have logic 7 on or off option now? Is this normal or a coding issue.
Can anyone with logic 7 in a CIC car confirm. Thanks in advance. Nathan |

So I did the recommended settings for my 07 E92 as suggested in the first post, turned up to moderate, not really loud, volume and instantly noticed a crackling in one of the rear speakers, now it wont go away. Essentially this setting blew one of my speakers. I'm guessing this would have happened eventually.

My stereo already sounded great but to I saw this post, used the e92 settings then tweaked them a bit. Sounds like a whole new system! Thanks to the op!

Very interesting! I'll have to experiment with this on my drive home.
Question: Why "Concert Hall" not "Theater"? I have those subjective terms... I wish it was just "Stereo" or "Surround". |
