I love the look of your Marantz receiver -- it brings back memories! I bought an entry-level Marantz receiver as a teenager (late '70's), along with some Marantz bookshelf speakers and a Sony direct drive turntable. I gave them all to my brother when I went off to college, but they were stolen a few years later. I love the blue-lit meters and the horizontal tuning wheel on the Marantz receivers -- so cool!
Does the Marantz do a good job driving your SB2's? I am using a 40W integrated amp to drive my SB3's in a medium size room, and it sounds great, but the top volume is limited. I am very impressed with the SB3 -- NHT makes great speakers at reasonable cost.
Thanks for sharing your systems! Best wishes, Todd
