HT and 2 channel in same room? 1 or 2 systems?

since the ideal 2 channel room uses diffusion to retain energy. whereas the ideal Home Theater uses mostly absorption to reduce comb filtering.

So many examples of both of those approaches. When I put mostly absorption in my HT it sucked the energy right out of the room. Now this room also had carpeting and seating that were absorptive.

Anthony Grimani’s recipe worked great for my room.

Here is a summary of what he recommends for home listening:

• Avoid LEDE

• 15% absorption

• 20% diffusion

• Carpet or deep absorption pit below listening position

• Bass traps in ceiling to ceiling corners

• Absorb first ceiling reflection point

• 3D diffusion on ceiling behind listener

• Absorb sidewall reflection if speaker is only a couple ft away from it

• Panels spaced evenly across sidewalls.

• Interleave absorbers and diffusers along sidewall. "binaural dissimilarity"

• Asymmetrical sidewall absorption. Absorbers face diffusers.

• 2D diffusers in front, 3D behind.

• Absorb center of wall behind listener "reduces mono-ness", with 3D diffusers on each side.

Example layout for 300-400 sq ft room

In hindsight, it might have been advisable to have this discussion prior to buying both systems, but hey, fecal matter happens.

Like others have said, having an integrated amplifier with home theatre bypass look after all the two channel output, along with the front channels of the home theatre is certainly to easiest solution. That way you need only one pair of speakers and get the best sound quality by far. 

Anyone that tells you that your AVR is sufficient to run everything is simply wrong. I tried that scenario previously by purchasing Cambridge Audio's top of the line AVR (CXR 200) and although it sounded pretty good in a vacuum, switching to a Musical Fidelity integrated for two channel was a 100% improvement.

I now have two completely separate systems that only share one cable. A RCA cable running from the L/R front channel pre out of my AVR to the HT bypass input of the integrated.

This type of setup will also allow you to run the HT sub from the AVR and the two channel subs from the integrated.

Unfortunately, your Willsenton R300 doesn't have a H/T bypass option so creating a hybrid system would require you to replace it, but if you are interested, have a look at the following site. Good luck.

I have a dual purpose room. I have an Anthem AVM70 with nice anthem multi channel amps for center surrounds rears and 4 ceiling.  I have a dedicated PSAudio front end and Focals all the way around. I could easily use HT bypass but what to do with the sub?  LFE with anthem or RCA out of pre. How to set volume and tune?  After much ordering I ended up with a JL Audio CR-1 xover.  It also takes care of xover for 2 channel and adds bypass for for HT at a push of a button. Allows for 1 sub. HFor the cost of the cr1 I could have bought more subs and used speaker outs to run but I do not have the room for it at all. 

Does your avr have a preamp out? ….. just connect it to the pre in to your tube amp.. run your mains off the tube amp.. run the room processor… listen to movies and tv with surround on and listen to music in direct mode. 
 

Done 

I have been a cinephile almost as long as an audiophile.

If you want them to share rooms, then you probably have to chose which one takes precedence. Putting a big monitor between your mains is a pretty horrible thing to do. I use a projector and a powered screen.

For me, this was my 2 channel system. I use the pre-out and I have used both HT bypass and and RCA switch (there are some very good ones, Manley probably makes the gold standard one).

I have the typical stereo - server > DAC > pre > amp.

My HT uses the same server, an AVR, and uses the pre-out to drive the amps.

I have very sensitive corner horns and I have used 25W amps to power these with great results in the past. My current amps are Manley Snappers (100W tube amps).

As for stereo using primarily reflection and HT using primarily absorption - this is pure rubbish. Both require pretty much exactly the same thing in terms of room treatment, and both require alot of it. The main difference is in speaker placement, and how the speakers interact with each other and the room.

When I set  up my system, I focused on front speaker placement. The rest of the speakers went where I could fit them, and I let the DSP figure out the timing. Not ideal, but still extremely good.
