    - Dual Digital and optical outputs with configurable frequency cutoffs
    - Built-in but bypassable room correction

    "Correcting" my two listening rooms is the most interesting and meaningful thing I've recently done with my Squeezebox system. I spent $75 for a UMIK-1 calibrated microphone and downloaded the free REW measurement suite. Implemented 3-4 parametric equalizer filters in each room using SoX and custom-convert.conf. Whole thing took me under an hour per room.

    My limited experience with room correction is comprised of the Audessy DSP in my Marantz HTR. it came with a microphone and a cardboard stand which a set up in the primary listening position and ran the set up. Based on how much better the surround sound sounds compared with the older Marantz that the new one replaced, I would say microphone based set up with a DSP is the way to go.

    Interesting discussion about Roon. I've thought about getting that at times for the simple reason of the expanded database and info. It would be interesting to know more about the recording and artists, but I'm so-so about the trivia aspect of music info, as in the drummer on this album played on another album and that saxophonist got sick during another recording in 1962 and threw up.

    For the most part, I'm content to hear the music that is being played at the moment.

    This seems like a good moment to make a reading reommendation. My son put me on to a book by Lace Clayton (AKA DJ Rupture) called "Uproot -- Travels in the 21st Century Music and Digital Culture". While I have a limited appreciation of much the the music under discussion, it is a fascinating insight into everything from MP3s, Autotune and FruityLoop software to Congolese and Berber music from Africa, Cumbia Sonidara and pre-Hispanic Tribal music from Mexico and so on, along with some interesting comments on the business aspects of the music industry. Can't say I'll keep it as a re-read or reference book, but was certainly an interesting read.

    That's a great idea Pablolie. I would also suggest the idea of LMS supporting MULTICHANNEL to stream through that HDMI interface :-).

    And make that room correction DSP powerful enough to handle the multichannel data in 24/96!

    The ipad app for Roon works nicely and shows all this info and is easy to navigate. the iphone app not so well (it is good for controlling playback, etc, but not good for browsing all this good info).

    and 3) How responsive is Roon as compared to LMS?
    1. with 95,094 tracks, from scratch it takes about an hour to scan library (about the same as LMS for me). At this point the music is playable. But after this, it does an additional scan in the background to create its own R128 (replaygain) values (both album and track) and generate wave form info. It takes about 24 hours to complete this task in the background. (this 2nd scan only happens one time unless you manually delete the database to start over...only new additions are scanned for this additional info, although if you change anything about the file (tags, etc.) it is rescanned by Roon just in case there has been some change.

    2. hmmm, not sure. The database it creates on my computer (which can be backed up and restored) is 3.46GB (this doesn't include my music files, only the roon database)

    3. equally responsive as LMS on both a i7 windows machine and an i5 linux machine.

    To try to answer the original posting - I spent yesterday at ISE2017 - Integrated Systems Europe, one of the largest AV trade fairs in Europe. It filled pretty much the whole RAI exhibition centre, but only one hall was Audio. Even Harman International were mostly promoting their smart retail store concepts. Everything was digital. Audio-over-IP (AES67, AES70) seems a big thing, but audio is definitely seen as just one of the many integrated "smart living" components. I had a bit of overload of Jetsons-like solutions to run my life.

    So forget optical. Forget audio cables (even Belkin was displaying their cat5/6/7 cabling systems). It will all be over IP, and using common protocols (instead of the current multitude of proprietary solution), but all a bit too oriented towards "lifestyle".

    So like Squeezebox then.

    Talk about ahead of its time.

    Gary, thank you for responding to my tedious questions. I really don't want to derail this thread by turning it into a thread about Roon but.........

    I do have a few more questions and comments.

    Regarding the "secondary" background scan: 1) is the replaygain defeatable since I don't use it nor do I intend to use it any time soon. 2) Is it during this background scan when Roon locates and builds the database with all the album/song information and generates the various links?

    As for the database size, I would guess that the final Roon database would end up being 3 to 4 times the size of the LMS database.

    And finally, can Roon be used/controlled from other devices (computers, tablets, smartphones, etc.) within the local network and will Roon provide the same information and links as when accessed from the computer that Roon is actually running on?

    Again I apologize for hijacking this thread and asking all these questions. Perhaps a little background information about my setup would help to explain my concerns. I have a Windows 10 computer that I use as the LMS server. This computer along with the external hard drives that contain all my music files is used only as an LMS server. On all my other computers and devices I use various programs (Moose, Muso, iPeng, Orange Squeeze, etc.) to access LMS and control the Squeezebox players in my home. So if Roon's fancy database can only be accessed from the same computer that Roon is running on then it would be a non-starter for me. In addition I have a much larger music library and I am concerned about Roon's ability handle a library of this size.
