Thx all!!
I think I got this figured out. The UDP-205 is going back on return. Bought a BDP 105 instead. (reasons, tidal support, Netflix, no need for 4k, better audio, no need to buy the Auralic Aries mini) The 105 has 2 separate analogue outs for stereo with better power supply and dedicated DACs. The UDP like the 103 doesn't have this only 7.1. I will use those and the 7.1 analogue out. All to Nuforce 7.1 channel preamp. 7 channels will then go to amp and the LFE channel will be split with a Audioquest splitter to speakers direct. The 105 while using stereo doesn't use LFE. While decoding theater audio does. Same with the multichannel Nuforce preamp. My only question was if I leave the LFE connected to the Triton ones will there be an issue when playing 2 channel. From you responses its seemingly not the case, The LFe channel will be ignored and frequencies <120htz (the crossover set on the Oppo, per Sandy's reccs; Speaker are set to Large always) will go to the speaker cable and the speaker will set the crossover. The preamp has 2 purposes for which people use this and the similar Parasound preamp for one analogue volume control (Oppo is digital) and second the ability to differentiate between 2 channel and 7.1 which I would be unable to do if I connected Oppo to amp directly. Reason for all this LFE is seemingly preferably for 7.1 but not for 2 channel audio. Triton 1's are to be set to Large in both circumstances per recc's.

Other settings Supercenter XXL crossover 80
4 Sat 3's set to Small Crossover 120

Thx much again to all.

In other words, could there be an acoustical advantage to making an LFE connection to the T1 (in addition to regular speaker connections) and toggle the oppo setting to large full range when listening to two channel from the Oppo (say a music concert video) and then changing the setting to something else when watching a movie that utilizes bass effect (say a star wars film)? If yes, what would that setting be?

Thanks, as a UDP-205 is on the horizon....

Hey, GDHAL

Good question. IN THEORY, with fronts set as large and no sub present, all LFE should be sent by the receiver/amp to the fronts. As lots of us have found, not all gear is willing to send FULL LFE to fronts, but will from sub pre-outs. I guess nothing beats a trial. Given that the T1's internal crossover is in the 100 HZ range, that might be a good start point. I presume you're playing through and powering the T1's with your Musical Fidelity integrated amp? With I presume short leads from the amp to the T1's, it probably wouldn't be too expensive a test. Not much to lose, maybe some extra bass to gain...

Happy listening!

Rick

Thanks Rick. Yes, I'm powering the T1s from the Musical Fidelity.

Are you saying that from a testing perspective, I could set the Oppo to fronts (but not "large" or the only two speakers) and some sub woofer setting with a cutoff at 100Hz, and run a separate RCA connection from the Oppo to LFE connections on the T1s?

Keep in mind my output from the forthcoming UDP-205 will be balanced connection to the MF. I am reluctant to connect to the MF via RCA to its home theater aux input.

So the most I would be able to do is connect Oppo>MF via balanced, MF>T1s via speaker terminals, Oppo>T1s via LFE.

Thanks!

Hi, GDAHL

My connections, OPPO to my Marantz AVR, are both analog 5.1/stereo, and HDMI digital. I can toggle back and forth, and get LFE/sub signal in either case when present to the Triton's subs via the AVR's sub pre-outs (T1's on sub 1, T2's on sub 2). So, in my case, when using analog feeds from the OPPO, the AVR just passes any sub/LFE input through to it's pre-outs. When processing HDMI digital feeds from the OPPO, the AVR's DAC does the work and again sends any converted LFE signals to the AVR sub pre-outs. All the Tritons are set as large, full range.

I spent a little time looking at the connection options on the back panel illustrations for the OPPO (is yours the 103, or 105?) and your MF. In your case, since you're planning to use the balanced stereo speaker connections between the current OPPO or future UDP-205 and the MF, and the 2 channel MF does not have a sub pre-out, it sounds some complicated to use balanced connects between the OPPO and MF, and also use a sub-pre-out on the OPPO to go directly to the T1's (in the case of the 105 the sub-pre-out is part of the 7.1/5.1/stereo audio out connections and served by a separate DAC from the DAC feeding the stereo only outputs including the balanced outputs). In the case of the 105, it would be simpler to use all 7.1/5.1/stereo outs with L/R's (not balanced) going to the MF, and sub out going directly to the T1's, with speakers left as large, so only the LFE component goes to that channel. That would be one way to at least test whether there is any potential bass gain for movies.... But if you want to use the stereo balanced outs (and there sure are SQ reasons to do that), then trying to run a sub out off the other OPPO DAC seems complicated.... HMMMM. A phone consult with OPPO may quickly answer whether both DAC's can be used simultaneously, or other options suggested...

Maybe others have thoughts/suggestions/experience that pertains...

Good luck!

Rick

I think GDAHL is fine. The advantage of the 105 (soon to be 205) is that he can use the separate stereo output. Not only is there the balanced advantage (one im skeptical of..) but the stereo analogue RCA's have separate optimized DAC's and output driving stages. His MF doesn't need a .1 dedicated LFE output. The Triton will see no signal from the LFE input and redirect all frequency to the internal crossover set at 100htz and the Oppo when in stereo mode will send all frequencies through the 2 channels and ignore the .1. When operating in HT 7.1/5.1 it will then use the LFE output thats connected directly to Tritons. His set up is similar to mine in some ways...
What incorrect above Rick is that the sub preout on the Oppo is part of the 5.1/7.1 not the stereo.
From the OPPO Website
"By default, the dedicated stereo outputs will output full-range 2.0 audio and downmix all multi-channel content into a 2.0 mix, and bass management only applies to the multi-channel analog outputs, which means that the player's Crossover setting will not impact the dedicated stereo outputs."
This can be changed to a 2.1 configuration with bass management the details are outlined on here:

Hi, Sam

I guess it's a semantics thing. The sub-pre out, as you correctly state, is part of what OPPO labels the 7.1/5.1/stereo analog audio outputs, probably because the L/R front outs in this set COULD be used in stereo mode also. This set of outs is serviced by a separate DAC on the 105 from the DAC that services the stereo only outs, including the balanced outs.
