speaker choice for new 20x30 audio room

I have a similar shop area with wonderful acoustics, how I don't know. Currently using the Peachtree AMP 500 ,  Soon to acquire an ATI 6002 AMP   Benchmark line preamp and their DAC 3B, with a pair of Tekton Double Impact speakers, with an SVS SB 4000 sub. Room filling sound, I listen at close to 100 spl. Not just loud but very DYNAMIC, and accurate, and precise in my opinion.  Solely Rock and Roll via Redbook CD and streaming USB Amazon HD through the DAC. Speakers are outstanding and you'll save a ton of money. You could jump up to the MOAB which have gotten many accolades about $4700 Robert TN  Good luck

I'll back up the suggestions on Legacys. I have chosen Focus SE's. Our room is 24X16. I also have 4 Legacy Subs as Bill Dudleton the owner and designer of Legacy happened to stop at my house on his way from a seminar in D.C. I explained what I was after, and he suggested subs from all corners. Not that the Focus SE's require subs, but I also listen to bands such as Metallica and if you want thump, you will really benifit from subs. I would recommend 2 of them no matter which speaker you choose.

Just wanted to let you know, I just came from a ATI 6005 and had some serious issues with it. It had a slight buzz from the day it was new. Not enough to send that 125 lbs. AMP back to California, but it was by no means a quiet amp. At about the 6-month mark, upon shutting it off you would hear a delayed pop out of the left rear speaker. ATI (John Barlow) was very helpful sending me a new board and walking me through installing it. Shortly afterwards a second board did the same thing, and I was forced into tearing it apart again. John explained ATI was having a bad run of capacitors and although very apologetic, it showed bad for their top-of-the-line product. I traded up to Legacys IV 7 amps and I am AMAZED at how dynamic, cool running and dead silent they are.

BTW, I auditioned those Tektons you have and although I sent them back and chose Legacy, they are a nice room filling product for the money. 

I have an audio room close to your dimensions - mine is 21ft by 27ft with 9 ftceilings. I am a Maggie fan for the last 30 years. Your system will shine with a set of Maggie 3.7i - to make it perfect add Duke’s Swarm sub woofer System - the subs have their own amp.. This should run you right at $10,000 all in. I am sure you will be very happy with the soundstage and vocals and detail.I do use Krell to push my two sets of Maggies - I have two Listening rooms. Referencing your floor options and dogs - I would use luxury vinyl flooring and then let your wife add multiple oriental rugs - my Wife Happiness factor went up in a big way for both Listening rooms with this tactic.

happy listening!

There are a few incredible products in that price range, even at the lower end of your budget.  

The Revel Performa3 F208.  This is an older speaker but is awesome sounding and because it is made in Malaysia, it is a killer value and at $5500 is at the lower end of your budget.  It will do okay with your existing gear and will leave you money to re-invest in some of the equipment...better amp/DAC/streamer

At a higher price point you could look at the Scansonic MB5 B.  It is a bigger sounding speaker with a ribbon tweeter.  They build a big soundstage with a large dispersion pattern.  It is a brilliant speaker that is very engaging.  It is a bit warmer in its tonal profile.  

I would also look at the Monitor Audio Gold 300.  Wonderful tweeter and brilliant drivers.  They are warmer than you would think for an AMT.  very natural sounding and are sort of a middle ground between the Revels and Scansonics. 

I am a dealer for scansonic.  I have no association with Revel or Monitor Audio
