Help setting up HT and Integrated Amp and Sub


Hi, all...
I have a bit of a hodge-podge system that I am trying to get set up and am having a brain-cramp determining the best way to wire things here...let me give a summary of the journey thus far:
- I live in a tiny little apartment, so my ancient full-range floor standing Polks do not fit, nor does much of anything
- Had a nice little home theater setup featuring Cambridge SoundWorks surround speakers and sub hooked up to a Yamaha RX-A700 HT receiver. Not bad, but I decided to get a little more audiophile as the quality was just meh.
- Bought a set of Harbeth P3ESRs and, wow, they are pretty fantastic...the sub became more important and so I replaced that with an SVS SB-2000.
So now I had the P3ESR, SVS sub and 3 Cambridge speakers (center and surround) driven by the Yamaha...not bad, but not great.
- SACD player (old Pioneer) died, replaced with Oppo BDP-103
- Got a Teac DAC to hook my Mac up to the stereo system
- Felt the P3s were underdriven, so got an Emotiva MiniX (pre-out from receiver into it onto the Harbeths)...sounded much better, surround and movies was bad though, so got 3 Cambridge Minx21s (very blah, but a bit better than the old ones) and left them hooked to the receiver...as is the sub
This was fine for a little bit, but I felt the receiver was really holding me back, so looked at integrated amps...tried a Musical Fidelity 3.5, but it doesn't like my power (even with a conditioner!), so gave it to my brother. Found a good deal on an Exposure 2010s2d and am where I am now:
- I want to connect the Oppo, the Teac DAC and the HT receiver to the Exposure, driving the Harbeths for quality stereo sound and leave the 3 other speakers connected to the HT receiver....but where do I connect the sub? If I connect it to the Exposure for use in music listening, I lose it from the HT setup so movies will suffer (as will the occasional surround disc I play). If I connect it directly to the Oppo, I need to play with the settings constantly and I lose sound level control (i.e. when I turn up the amp/receiver, it won't get louder too).
I did buy a fairly good quality RCA Y connector thinking I could run from both the integrated amp and receiver, but it introduced a pronounced hum, which I am assuming is a ground loop somewhere...

At this point I am getting all confused and it is annoying, as it is a feeling I am not used to. Anyone have any ideas on the best way to connect all this? I mean...I want pure audio through the integrated amp, with the ability to watch movies and play surround content through the receiver...
Thanks in advance!

Thanks for the suggestion...not sure that would work for me, at least I would prefer it to be switchable rather than auto-sensing. It would theoretically be a bit more solid a connection than a mere Y-cable.

I was in a similar situation as you - wanting to incorporate a subwoofer into a setup that has an AVR for movies (and the LFE output to the sub), but also ’better’ audio for 2-channel listening with an integrated amp.

It is too bad you couldn’t get the MF A3.5 int amp to work for you, because that amp has an HT Direct feature that would have allowed you to do exactly what you want w/o resorting to switches and such.

I couldn’t tell from the Exposure specifications whether it has an HT Direct (aka Bypass) feature or not.

If it doesn’t, then I think you have to use a manual RCA switch device in front of your sub with the outputs from the AVR and Int Amp.

I assume you plan on connecting your AVR L&R front preouts to one of the RCA inputs on the int amp to drive your front speakers?

Yes...the Exposure 2010S2D does have a HT 'bypass' input (prior versions did not), which I do plan to use (if only for the convenience of using just one remote when adjusting volume on surround programs). The only thing there is what to do with the sub then...it is already connected to the sub pre-out on the receiver, but is not connected to the integrated so on stereo playback straight from the Oppo to the Exposure, I do not have the sub (and believe me, the Harbeths NEED the sub, as they only go down to about 70hz, and really trail off around 80hz).

It is sounding more and more like I need to do an RCA switch...now I have to find a good one that doesn't cost an arm and a leg and doesn't have a terrible impact to sound quality (so much for the wonderful expensive sub interconnects I bought!). I just have this feeling there is something stupidly obvious here that I am missing. Well, other than just getting two more Minx21's and making the stereo system completely separate (which would still lead to a connection issue with the darned sub!).

Here's a manual switch that should work. Just use 2 of the inputs for Integrated and HT receiver, then output to the sub.
