I'm more a headphone kind of guy, though lately I've been after better stereo speakers for my room.

The other day neighbours down the street were throwing out their old (~1975) system. I managed to get 2 sets of stereo speakers.

One was the Sony SS-1250 http://audio-heritage.jp/SONY-ESPRIT/speaker/ss-1250.html

The other was a Pioneer CS-311. Luckily they seem to be working fine though they REALLY need amps. I tried running them off an AV Receiver which is supposed to handle 40Watts per channel but they sound a little weak but that's probably due to an impedance mis-match.

Anyway, I'm after making 2 sets of amps for each pair of speakers, (is it even worth it for these ~1975 speakers?). So I just generally want input from you guys, to see whether or not these speakers are worth making an amplifier for. They sound really bad at low volumes, but at high volumes they are much better than my current set of shitty Sony SRS-A202's.

So if there is anything anyone can offer, I'll gladly appreciate it!

I have some free time this week so I was googling around for a DIY forum, i'll have to check out head-fi later tonight.


Cheers

Sam

Hi Sam, well you got them and they were free, so have some fun with them. For an amp, a diy chipamp (~50W) are relatively inexpensive and should work well.
Cheers

My experience with 70s gear is that high-feedback amps of the same type as were common during the era work better, I have a pair of Choral SA-7 driven by a Technics SU-8600 and they match up great, much better than a newer Arcam alpha 9 I used to drive them with.
