In learning mode...


What makes a good DAC?


Comparisons of ERC and other DACS - link

Quote:

So, what DAC measurements correlate well with subjective improvement in sound?

Not exactly high up on the list of technical prowess, but I got it done.

Since I just did a Radiance FW update, I haven't tested it out to make sure it's function (now I need another RS232 cable), but it should work.


Mike

Picture:

- MA blank plate

- MA UNI-1C & Switchcraft adapter

- Lumagen RadianceXE

- iPod dock

- Surge-X SEQ (non-MOV) surge protector


I finally used this external RS232 for a Lumagen RadianceXE FW update.

It worked.

No problem.

Thanks Wayne/funlvr1965 for suggesting it.

I'd still like to see a front FW update port incorporated in the Lumagens...

Your welcome Mike, it makes rackmounted gear so much easier to update this way. I also update my Anthem D2 processor using a second installed pin rs232 port. Next is getting the ethernet port to go live, not high on the list currently but will get it done eventually.

Wayne -


So remind me of your setup for external (front) connections:

- RS-232 - Oppo BDP83

- RS-232 - Anthem D2

- Ethernet -- is this because you can't hook up your ethernet from behind the rack?


Will you be using an ethernet switch to hookup to your various components?


I had to crawl behind my bookcase (through bass traps) because the pull out MA rack is too heavy for one person to pull out (maybe not for Wayne
) and pushed in a loose HDMI for my XBOX 360.

I then connected to my computer and played MP3s from my music library and watched some family pics.


I realize that is all very basic stuff for people, but I hadn't done it before.

Mike the RS232 connections on the front of the plate is for updating the lumagen and the Anthem D2, I did not get the RS232 port on the Oppo like you did. The ethernet port is going to be so I can plug my laptop into for direct ethernet connection as opposed to wireless, it will be connected to a wired router and the ethernet feed from that will come from my original router 2 floors up in my office. Im sure that all makes sense

Got it.

I misspoke/wrote.

I knew you had the Lumagen and Anthem.

The Oppo doesn't update via RS232, that is only for control.

Your wireless must have interference to make it tough to reach the basement.


Cool.

Mike I'm just not a big believer in firmware updates being done wirelessly to begin with, I do get a wireless signal in the basement theater but yes at times there can be interference in my area.

I was digging around in another thread and googled some old speakers --
Infinity SM-152.

I found this AVS link (and specs -- not even on the Infinity website support):

Woofer: 15" (381mm) polypropylene coated
Power Rating: 10 - 300 watts
Frequency Response: 44Hz - 25kHz (+/-3dB)
Midrange Drivers: TWO - 4.5" (114mm) polypropylene coated
Tweeter: 1" (25mm) high-output polycell
Nominal Impedance: 8 ohms
Sensitivity: 102dB (1 watt/1 meter)
Crossover Frequency(ies): 500Hz, 5.5kHz


------

Man, a 102 dB sens -- no wonder they were great for college house parties!



It's also interesting to see that what I thought had a lot of bass had a -3dB point of 44Hz. Nothing beats a dedicated sub.

TCA WAF-1 vs. av123 ELT525M Mini-monitor Comparison

TCA Ordering: TCA efficient, fast response and delivery
TCA Packaging: WAF-1 was well packed, double boxed.
Exterior: I like 525 veneer and corners better.
525 more narrow, but both are nice.
One of my WAF-1 grills came off. TCA replacing.

Caveats:
- suboptimal setup in office - but how I am really using my system
- no A/B switch
- not SPL or voltage matched and unblended
- known biases - I really liked my 525M's before this. I like the TCA company.
- Early comparison and I'm not a "real" audio reviewer

Sound:
- Immediately noticed that the WAF-1 slightly louder than 525M (likely due to sensitivity difference 83 vs. 86 dB) - adjusted by ear to compare
- WAF-1 more neutral, and clear/articulate
- WAF-1 more forward

Conclusions:
- either WAF-1 or 525M are great bookshelf/office speakers
- the 525M may be more forgiving of bad sources (warm/softer)
- the WAF-1 in comparison is more clear/articulate/forward
- the 525M is lower sensitivity
- aesthetic styles are different

Other comments:
- a front ported system might be easier to integrate in some bookshelf type settings
(however, craigsub noted that plugging the rear port results in a FR cutoff around 75 Hz, which is okay if integrated with a sub -- link )



iPhone Pics....
(iPhone doesn't capture how good the speakers look)

My APC AV H10 surge protection arrived.

$79 + S/H from Circuit City online.

Nice.


Old Denon AVR removed for tinkering or recycling.

Updated Oppo BDP-83 beta FW.

Awaiting a chance to do the new FW production update to Lumagen (allowing PIP).


Also, updated some posts with pictures to embed them.

Cleaned up post #1 and added an index -- I got the idea from someone's HT thread and I'll credit him when I remember whom.




Mike


PS - Wife got home from surgery today, so just chillin' out at home.

Empiric rationale for using 4:2:2 for Oppo BDP-83 posted in Oppo thread:

Link


Oppo BDP-83 - 4:2:2 better than RGB better than 4:4:4


From that post (minus pics):

"I have compared the performance of the different color spaces available in HDMI using the Spears and Munsil Zone Plate and Multiburst tests : RGB video levels, YCbCr 4:2:2 and YCbCr 4:4:4.

The Oppo BDP-83, firmware 905, is connected in an Eizo HD2442W monitor through HDMI (1)

The differences are small. I don't know if this could have any visible effect in a movie. So it's mostly an academic exercise.

YCbCr 4:2:2 performs best, followed by RGB, followed by YCbCr 4:4:4, which darkens the most the edges of the pattern.

I've taken some pictures of the screen (2). The pictures are intentionnally blurred from the lens in order to avoid extra moire and bandwidth issues in the camera."

Thanks.

I think it is fixed.

I dropped off the old Denon AVR at Best Buy for recycling.

New FW update for Lumagen RadianceXE is cool...

Link


The PIP mode does moves the PIP window around the screen.

The default is a 3x3 grid:

0/1 2 3
4 5 6
7 8 9


That is, Mode 0 (or 1) in left upper quadrant (LUQ), 2 in upper center, 3 in RUQ, 4 on left center, 5 in center, 6 right center, 7 LLQ, 8 lower center, 9 RLQ.


As far as I can see you can't move the position "on the fly" or change size or transparency without going into the menu.


In Menu -> Other -> Pip Setup

you can change/select:


- Mode#

- X

- Y

- Size

- Density


X, Y change position

Size goes from 10-95%

Density - 10-100% - changes the transparency



Very cool.


WISH LIST:

- PIP SWAP function

- analog input support (not just HDMI)

- "on the fly changes" - eg -- arrow keys to move the PIP around the screen and/or change size as well.

- 50% split screen

Post 313 yes, 312 no. Only pointing it out because I like pictures and your thread is so well organized I hate to see errors.
