Lots of detail, great imaging, not much bass?

B-limo,
Just wondering, why not simplify system since moving into smaller quarter?

Get an excellent quality integrated amp with tone controls ~ (adjust bass as you wish) +
loudness boost (for late night/low level listening) + built-in headphone amp (ready when
adding one). This, I believe will suit your purpose better, whilst giving more flexibility and
less clutter too (happy fiancé). Only then on to speakers later ~ when/if still needed.

Something like a Luxman / Accuphase / Mc Intosh unit would be nice. Just saying..

*Btw. House music with little bass is like living with no soul. So you still do need that bass
reserves for when no one's looking! ;)

Soix, thanks for the input regarding bass transmission, as I was thinking that the triple layer, green glue would help with bass. I think really what I need to do is just wait until I move in and then do some sound tests with my music playing and then go down in there bedroom to see how bad the situation is going to be.

I really don't get why home builders (especially custom home builders at the price point that this home is; $800-$1m?) don't spray insulation in the floor joists in an attempt to help withnoise transmission through walls, floors and ceilings. It sure would help homeowners enjoy thier homes more if thier teenagers pounding techno music (or in this case, my pounding techno music) throughout the whole house. I love techno / house music but I can totally understand how utterly annoying it is when all you can hear is "boom boom boom boom boom".

B_limo, knowing all the facts now I think most important is having enough gain from your system and damping the room as you have wisely decided.
I've lived in apartments (new construction) where neighbors complained about my TV thru their walls.

So what you're telling me is that if I had more gain I'd get more detail, better imaging and less bass? Because that's what I'm after. And do you know how much gain I have in my system? Should I just replace my lightspeed attenuator, one of my favorite pieces? Ummm, okay...

I'm not saying to replace anything; what I mean is some of the techs on this thread have voiced this concern and maybe they can offer advice since it's all about system synergy.
(with more gain, you would get higher efficiency and not less bass; that's not the goal; you would have more control).
