Replacing from Hurricane Sandy

If you have 4k-5k to spend, then I'd suggest tying to get a killer, used sub for around $1,500. Revel, JL Fathom, B&W, Paradigm, SVS among many good ones out there.

For an amp, Emotiva gear is getting really good reviews for the money. So like Rotel, they are considered a great value. 'You can get a 5 or 7 channel amp with plenty of power for under $1,000.

For Bluray, if you want the best out there and you don't need analog out, then go for the Oppo BDP-103 for around $500. If you want to save a few hundred, then go with a Panasonic or Samsung Bluray for $150 or so.

For a pre-pro, you can try Emotiva in-house and see how you like it with no obligation. You can also go for a used Integra 80.2 or 80.3. The video card is the only difference there. Brand new the Integra is right around $2,500 or so I believe. Used is much cheaper.

If you want less expensive, the Marantz pre-pro has gotten simply excellent reviews.

I think with the pre-pro it will come down to a choice of EQ options. I'm a big fan of EQ. It works and works very well in the bass regions. The Rotel doesn't offer it on their pre-pros so I'm hesitant to recommend a new Rotel for you.

I uses Revel B15 sub in a room far larger than yours and it is amazing. You can optionally consider 2 subs but it may kill your budget.

I have a Lexicon running my main HT setup but I use an Emotiva x-100a mini for my zone 2 and zone 3.

Kal in stereophile gave the larger Emotivas a spin in his Stereophile column and they were well reviewed. Just a suggestion since you have a free in home.
