Ask S&V

I recently ordered a pair of ER20 "high fidelity plugs" from Etymotic, a universal-fit, low-cost option ($12.95) that the company claims to reduce sound by approximately 20dB in all frequencies. Have you ever tried them? I have also ordered a pair of custom-fit sleeves for my ER4s from ACS Custom. (When I was in the US, I went to an audiologist for my ear-canal impressions.) Because I had my impressions taken, I can also order a pair of custom-fit plugs with filters. However, they are more expensive ($185). Do you recommend the custom-fit ones?

I promptly went to BrandsMart just to look at the two and finally decide which one. Of course, BrandsMart had neither model, but then the salesman tried to sell me on LED, which I had not researched before. He said plasma technology is on its way out and LED was the wave of the future, and that the Sharp LC-70LE735U was what I needed. What's your take on this?

Also, does it make sense to buy the same brand of TV, sound system, and Blu-ray player? Lastly, not being a techie, is it really hard to connect all three?

In terms of projectors, I'm looking at the Epson PowerLite Pro Cinema 9700 UB (2D, $3,100) and 5010 (3D, $3,000) on an Elite screen (120 inches, $500). Or should I get a Sharp 80-inch LED LCD ($4,300)? The most likely A/V receiver is the Marantz SR7005 ($1,500), which is not THX-certified; is that okay? I've decided on the Definitive Technology Mythos STS SuperTower system ($4,000 for 5.1, $4,500 for 7.1). Finally, do you think the Universal MX-880 remote is better than Logitech Harmony universal remotes?
