Went to an estate auction last Friday evening that had a 170 along with the complimentary XP55 speakers. Was there 4 hours and I knew they weren't gonna get to it till next week and left. Sure enough it is still on the auction block for this week so I'm hopeful of getting it for a low price. It is nearly perfect. Comes from a Law Professors estate at the University of Arkansas. I'm wondering if these old SS Fishers aren't somewhat the same sonically as the HK's?
Pioneer SX-626 - Maybe not exactly under the radar but these little 20 watters are worth picking up if you see them. They are usually pretty inexpensive and offer a lot of quality for the money. Fantastic tuner, nice "earthy" cap coupled sound plus pre-out/main in jacks so you can use it as a preamp/tuner.
At 22 watts per channel I love the sweet sound of the Harman Kardon 330B. Plus, you can use the preamp separately.
Currently listening to my 330B right now. Picked it up last year about $50.00. Dirty, but cleaned up with De-oxit. My hk730 and 670 are both in need of attention, so I pressed the little 330B into service, and it's just a lovely unit.
Running iTunes thru Airport Express into Schiit Modi, and from receiver into Wharfedale W90s. VERY nice!!
Under the radar? Pretty much anything that doesn't say Marantz on it--that is until you post about it on here.
