SHOULD it be possible to have the UNUSED speaker outputs terminated with some kind of 8 ohm (give or take) maybe up to a 5 watt resistor when NOT selected as the speaker output?
That would PREVENT a mode in which 'accidents happen'.......
For example? You have 2 amps, one of which is tube...the other SS......You have them switched thru a speaker switch......I see bill uses a break before make switch......Excellent and will prevent interaction of 2 amps.
But why not have the 'not' selected amp than terminate in a dummy load. that way IF SOMEONE decides to turn the amp ON.....it will still have a load.....and wont 'zorch' itself.....
I need to sit down with a sheet of paper and get my active brain cell on it....

Is the ‘Coax’ coming out of the TV actually HDMI, or is it TOSLink to Coax?

I have the hdmi coming out of the Apple TV 4K going to a splitter that provides an HDMI feed on to my projector and a coax output to my McIntosh D1100 digital pre/dac for audio. The projector throws an 11’ wide by 5’ high image for movies above the tv which is mainly used as a Roon monitor and REW display. The LB200 lightbox contains the Mac Mini, ATV and splitter. Latest system pic attached....  |

Recommendations in that regard would be useful to me. |

Thanks, 405 - I'm probably not the best person to ask - I got an Epson H852A LED projector (refurb from the Epson store for a good discount) several years ago that has and is doing a great job. Big, clear image from about 15' back.
Best,

Very impressive audiobill. Love the diagram. Surly you know the business. Thanks for suggesting the Magnepans..to me the BEST musical speaker out their. |

No, the center image from my speakers has always been strong. My system is really two channel with movie support.

I've compared these dacs using my MC275 180 wpc tube monoblocks and my MC452 450 wpc amp through my Maggie 3.6/r, Dynaudio Gemini, and PBN Montana EPS speakers as well as my Sennheiser HD-600 headphones. Using REW, my room isn't introducing important sonic anomalies. After informal level matching, I hear very little, if any, difference between the Yggdrasil and the Sabre dac built into my MC2600 tube based preamp. Maybe here or there I think I do, but after double checking I don't. My theory is that a critical part of a dac is the power supply and the analog output stage, and with the McIntosh tube pre the power supply is of course very robust and Mc certainly knows how to build a great tube analog output stage. The Mc filter choices in their Sabre dac implementation may well reflect their sonic priorities as well. Claims of Sabre dacs being "bright" just aren't supported in my system(s). Since Sabres are used in so many dacs, it seems hard to make such blanket judgments. I plan to keep both of these dacs actively in my system; I can easily switch dacs on the fly. I like lots of options in my listening as you know. However, the McIntosh D1100 easily trumps these two for digital conversion. Very detailed and deep, spacious sound with no noise. Because it is a full-featured digital preamp, it also sports a very robust power supply and output stage. If the D1100 is affordable to a buyer, the best I've ever heard. Check the design and features online. Findings - make sure your dac and/or preamp has a very robust power supply and output stage, it matters. And including a dac into a pre is a great idea; it leverages strong existing circuitry and can be ignored if dacs evolve much further. Hope this helps! Do you employ any form of EQ, like Dirac, in your system? |

Yes, I created filters in REW for a flat in-room response, then loaded them into Roon’s convolution engine. From there, added a PEQ filter in Roon for a +6db low shelf from 125 hz down to 20hz to achieve a target curve I like. My room has room modes at about 60, 120 and 660 hz that are neutralized after this process. I got this from Danny Dulai at Roon, Really sounds wonderful to me ! For Vinyl, I just trim the bass and treble tone controls in my C2600 preamp just a tad to suit.

I own Magnepan 3.7i speakers and I have to agree with audio bill that the center image they project in home theater is great, but only if you are watching a movie by yourself. Otherwise, when there are other viewers in the room, I use a center channel speaker. I hope to buy a Magnepan center channel and add Magnepan LRS speakers for the surrounds one day. Obviously, the 3.7i's by themselves present a more cohesive sound than they would combined with a non Magnepan speaker. One thing is certain, the big Maggies project an unbelievable phantom center image for music. |

Certainly this would be worth it to me. |

For Vinyl, I just trim the bass and treble tone controls in my C2600 preamp just a tad to suit. Roon has amazingly good EQ. I have found it possible to use Dirac and then overlay with slight EQ by Roon to address some otherwise difficult to fix frequencies. The EQ for Roon ARC is also very good. I was skeptical that Dirac would work well with my Magnepan 3.7i's, but I am very pleased with the results. MarcL deserves all the credit for Dirac advice relative to Maggies. |

One thing is certain, the big Maggies project an unbelievable phantom center image for music. Something that often gets missed in music is that the center channel is underestimated for its musical impact, especially when it’s a good one with plenty of power delivered to it. My center channel is always in play with music as well as film and often use it to steer the imagery in music as well |

Certainly this would be worth it to me. The 3D from an R3000 JVC projector is stunning. I had no idea it would be so good. I believe all 3D BluRays are 1080p, but the image with the 8K upscaling is silky smooth. If you want advice from someone who really knows projectors call Mike Garrett at AV Science. |

Between the music integration, multi system management and dsp, Toon is a steal imo
