I need to buy a complete system.

The reason I suggested the Harbeth M40.2 and not my personal favourites the Quad electrostats is that by the description this is for a very large room where the Quads would struggle.

A lot of amplifier power would be a good idea in this case. Alan Shaw, Harbeth’s designer, recently demonstrated the M40.1 in the Netherlands and the power meters on the demo amp indicated more than 500 watt per channel. Fortunately watts do not have to cost much if you use pro audio amps rather than fancy overpriced high end hifi. A good example would be the Yamaha pxx00 series. See here for a test of the 2x350 watt rms P3500s that until recently sold for about $500 and performed better than some boutique amps costing ten times as much: http://www.homecinema-fr.com/forum/amplificateurs-de-puissance-haute-fidelite/mesures-ampli-yamaha-p... I bought the 2x250 watt P2500s for my son and the sound quality is perfect. Alan Shaw has long argued that Harbeth speakers will perform perfectly with any properly designed amplifier. He has also argued repeatedly that you do not need fancy expensive cables. If you think you need them, your system has a problem.

I would suggest if you have $20-25K to spend on a new stereo spend a bit of money traveling, either to Hifi shows or good dealers. Take some time and do some listening buy it once and buy it right if you can. We can recommend gear until the cows come home but ultimately your ears need to decide for you. Good luck!

I plan on taking my time and traveling in the fall to RMAF in Denver.  I am in no hurry per se.  Are there any other Hifi shows that is sooner than RMAF

Room treatments do not work in my house.  The house is not designed for them

I appreciate all the responses.  Thanks
