Isn't the L-70 a combo CD/receiver? I had a NAD 3020 receiver and a NAD CD player. No complaints, honest/inexpensive products. NAD compares in the audio world to Nissan in the auto world.
The Linn would be several steps up in price and more quirky. Not sure about reliability. It would be a Saab.
(I've owned both brands of cars mentioned, no slams intended.)
For relatively inexpensive, but very good HT speakers I'd highly recommend Ascend Acoustics CBM-170's. They're about $160 each, 12" x 8" x 7" 2-ways, 70 - 20,000 Hz, 89 dB/w/m, 8 ohm. Black pebbled vinyl finish, 1" recessed tweeter/6" aerogel woofer, rear 1/4" x 20 threaded insert. High content value, just not much to look at. Sonically they blow away any B&W, Paradigm, or Dynaudio at 3 times the price. Those provide black and white outlines of music, the Ascends paint with color. I've got a 2-channel HT setup with a cheap DVD and UNSUCCESSFULLY factory reconditioned Harmon Kardon stereo receiver with the Ascends and a Hsu VTF-2 sub. The sub is definitely the weak link 9 (when the HK is working - left channel has blown twice after maybe 20 hours of use).
