We've owned B&W speakers since late 80's

Well if you can wait a bit since your in Denver on October 6-8 will be what's widely regarded as the country's best audio show RMAF.

Also not sure why you call Moon amplifiers, Simaudio is the name of the company, middle of the road? They are generally highly regarded and I daresay higher than B&W in certain circles regardless of their respective prices. What is your overall budget for all of this? Looks like Listen Up also have some other solid speaker brands, Magnepan, Tannoy, Sonus Faber, Golden Ear (a newer brand that a lot of folks here seem to like) etc. Take your time and go in there with open ears and listen to some stuff. Don't be sold, listen and buy. Trust your ears.

@roxy54 And that is why brick and mortar dealers are vanishing. Don't do that please find a dealer that you like if you can and work with him. Listen to as much as you can and take good advice. The support that dealer. Good luck.

Great and good luck and you could easily find yourselves getting better sound for less money than you originally would have spent.

@lalitk Thanks I am lucky enough to live near a great dealer myself and have come to realize had work with them years ago rather than churning through dozens of used components I would have likely saved money and had a better system sooner.
