I've been buying from Magnolia Hi-Fi happily for over a decade, across several states and many residences. The chain in general has (or can have - see my review of the Bellevue store) great prices, excellent service and good equipment. The salesmen know their stuff.
Okay, that said, the Lynnwood store isn't so great. We've been in there about four times. Each time something was off. Once they were certain they have an item in stock, and they didn't. Another time the salesman just creeped my wife out. Last night we were there, with test material, to buy new speakers but we didn't believe our ears on the comparison. And with good reason - the systems were wired wrong!
That doesn't make Magnolia a bad store. I still bought from them, today in fact. But not from the Lynnwood store.
