post #5011 of 5782
I have been sending 24/192 audio over hdmi from an Oppo bdp93 to the SSP-800 with no issues for months. The SSP-800 says it's getting a 24/192 signal.

I hooked up a Mac Mini tonight (latest model), and the mac's Audio MIDI setup is only showing the SSP-800 as being capable of 96khz over HDMI

Trying to play a 24/192 album (Norah Jones from HDTracks) froze Audiofile's Fidelia application.

I was under the impression that the Mac Minis can output 24/192 over HDMI. I know the Classe can accept 24/192 over HDMI from the Oppo, so what's going on with the Mac Mini?

My old (2009) mini does 24/192 over Firewire (Weiss DAC2), it doesn't have HDMI. But I did read on Computeraudiophile.com that up to 8 channels of 24/192 are possible from the HDMI of the mini. Maybe the MIDI displays this wrongly as 24/96?

Hello everyone. Picked up my Classe SSP-800 today from my dealer. The problem I have it does not play DTS HD MA format. The others like Dolby are ok. The signal comes from oppo BDP-93 through 1.4 HDMI. Firmware 3.0.2 build 0102. I guess it is something simple but I struggle to figure it out. Sorry if it was discussed earlier- could not find it. thank you in advance for all your help.

Bitstream from your Oppo BDP-93 into the Classe? Is your secondary audio off on the BDP-93? Also what does the screen on the SSP-800 indicate when you select the mode screen? You tried the discrete audio setting on your SSP-800?

Problem solved. Updated OPPO software. All working now. Thanxxx

Try the search this thread function at the top of the thread.There is a brief mention of it from Roger who has actual hands on useage.

If any Classe owners are interested, my CP-800 stereo preamp processor is up for sale here and on Audiogon.

PM with any questions.

Thanks

I have an Anthem D2 and I am looking to buy a Classe SSP-800.
I asked the dealer how they EQ your room with the manual
EQ on the SSP-800. He said the use a real time analyzer
With a sound pressure meter and EQ it for a flat response.
Now reading Kal's review of SSP-800 he recommends XTZ room EQ tool.
Would it not be better for the dealer to use a room EQ tool
Versus just going for a flat response with a sound pressure meter?
What are owners experience with this.
My room does have some problems so room EQ is necessary.
Thanks for input.

^^ The nice part about XTZ is that it tells you the PEQ settings to use, then can measure your results against the simulation to verify results. I agree that would be more effective, particularly in rooms with bass resonances (and whose does not??), than dialing for flat. REW can do a similar analysis, but not as easily.

I had commented to Classe that it was a little messy to figure how to get a test signal into each channel alone, so they added the wideband pink noise generator that comes on automatically when you enter the channel's EQ menu. That can work well with a decent RTA (better than 1/3d octave) for the main speakers. If the RTA can sample and average the space around the MLP, that can lead to better results than a single-point measurement if the responses are not uniform.

No matter what method is used, lots of listening is needed to really decide if the tuning was successful or not. One thing that's nice is the SSP can store the entire user settings into a separate memory. Then you can mess around with the settings, and if you want to erase all that, just recall the stored settings. This is done from the service menu accessed by pressing Menu>F1>F2>F3>F4. Unfortunately, it does not have 2 memories so it cannot alternate. To do that, you have to save/load from a PC. Then you can save infinite setups, but it takes a few minutes each time.

Agreed.  One thing you have to decide is how to allocate your EQ resources since they are limited to 5 PEQ filters per channel.   In my NY room, I needed only 2/channel for the bass but one could easily use all 5 for the LF if the room, such as my CT room, demanded it. So, initial use of an RTA or the full-bandwidth modes of XTZ (which also includes an RTA) would be informative.

I have had good success using XTZ, as well. For my room I have used 2-3 bands per channel, to help reduce the room modes only. I have not tried the "pink noise gen", that was implemented with the latest firmware update. I will have to experiment with that using XTZ's RTA.

^^ XTZ's RTA is only 1/3d octave, so it is only usable for the broadest corrections (like Q=1 in the PEQ) at frequencies above 300 Hz or so. Don't try to make the bars even if one is sticking out.

Gotcha! Thanks Roger. I'll check it out.

Yes but I was recommending its use only above 300Hz to determine if any of the 5 SSP-800 filters are needed or if all can be devoted to sub-Schoeder frequencies.  

post #5027 of 5782
Thank you for your answers. I have to be sure I get
The right answers by the installers of the dealership before I buy a SSP-800.
I would be an unhappy customer if the Room EQ was done
Inproperly.

I never tried it, but I wonder if it would be better to use XTZ to drive each main speaker "wideband" (no crossover applied), to see how the room/speaker behaves below 300 Hz. And if there is particular mode there that XTZ identifies, then it will prescribe the corrective filter. That would seem to be a much more sensitive test than using the RTA.

I thought XTZ only did measurements but didn't suggest what to do?

Yes it works with the Oppo BDP-95.

I know it works with the Oppo BDP-95. My original post said I have no problem playing 24/192 from my Oppo BDP-93.

I'm having a problem playing 24/192 from a Mac Mini. I thought that you were going to try from a mac Mini. Misunderstanding...

Apple's documentation says that it should support 24/192 over HDMI

http://support.apple.com/kb/HT4214

Which type of audio works with HDMI?
Apple supports 8 channel 24-bit audio at 192kHz, Dolby Surround 5.1 and stereo output."

But I can't get my Mini to select anything in Audio MIDI setup above 96khz. I'm not sure if this is a Classe issue or an Apple issue.

Does anyone else have a Mac Mini with HDMI out?

I have done exactly that for use with the SSP and a few other prepros.  However, what I was suggesting was to use one of the wide-band analysis functions simply to assess whether there were upper band issues that needed addressing.

It generates suggested filters below 300Hz and will simulate their effect, as well.  Very useful with the SSP.

I have a Powerbook with Retina Display with HDMi. I know the CP-800 is limited to 96khz frown.gif Never tried it with SSP-800 if I have the time I will try this weekend

If I understand correctly it will tell you what to do for the EQ so you just have to plug them in and Voila?

Also I was wondering is it better than Dayton Audio OmniMic V2 Precision Measurement System

Pretty much.  I would remeasure after putting in the filters to confirm that they did accomplish their task.

Depends.  They do different things and work differently.  Not so equivalent that one can say that either is superior unless you define the tasks precisely.

This (http://www.stereophile.com/content/music-round-51-page-2) is my report on the original release version (much improved upon since) with some comparisons. 

post #5039 of 5782
The SSP-800 accepts 24bit/192kHz input on HDMI, but it will internally "downrez" to 96kHz. This is because the DAC's used work best with 96kHz signals (less jitter and other artifacts). I would not think to much about it. You probably will never be able to hear much, if any, difference between 96kHz and 192kHz. The important thing is 24-bits. This gives you a much higher dynamic range than 16-bits.
post #5040 of 5782
I'm not really concerned that I'll be able to hear the difference (I doubt I could). I am just curious which component is to "blame."
