Low End Bliss

Since getting bitten by the hi-fi bug I have given thought (and posted some questions) about how to improve the system down at my cabin which was a Toshiba SA-2500 that I got in 1980 and some Bose 2.2 bookshelf speakers I got around 1990. 

Since getting my hi-fi system the 2.2s became increasingly less pleasant to listen to.

I first replaced the 18 awg speaker wires with 12 awg 100% copper low o2 wire. It made no difference. Then I got them off the floor onto shelves at a better right height  which helped but due to room issues couldn't get them at the right height.

Since I'm trying to do this on the cheap I researched my old SA-2500 and it has gotten glowing contemporary reviews (really low distortion measurements) and good reviews in its day even though it was a mid-fi unit at best. So I've decided to keep it for now. Plus, it is a pretty unit and fits the decor of the cabin okay.

Then I decided bookshelf speakers were not an option since positioning was so limited. So I looked for towers but they needed front or bottom facing bass ports due to required proximity to the back wall. I found a pair of Polk Audio Monitor 70 towers on Craig's list locally for $180 for the pair, in excellent condition. They were Polk's low end tower. Decent reviews. Around $500 new. Put good banana plugs on the 12 awg wire and made jumpers with same (just for the heck of it).

Got a $15 Toshiba CD player at a Goodwill shop. Headphone jack to RCA 'Y' cable for laptop input. When I upgrade the Schiit Modi 2 Uber in my homes system I will take it to the cabin.

Bottom line is that I'm thrilled with the SQ. Not hi-fi but also not critically wanting like the little Bose. There is actually a soundstage. Bass is not muddy but it is a little boomy. I will try putting some socks in the bass ports to see if I can tune that a little.  Highs are a bit bright. Some of this can also be attenuated with the bass and treble controls. They do quite well for low volume listening also. The overall SQ is obviously nowhere near my home system but still pleasing and a huge step up from before. 

The SA-2500 needs three bulbs replaced. A service manual is on the way and I will do that part myself and it should be restored to its prior glowing splendor.

Thanks to all at Audiogon far all advice received to date.

One of the things that has helped me gain some confidence with this hi-fi stuff was that I originally had my main system at the cabin.

One of the things I immediately noticed is that I could get to a sweet-(ish) spot with that system but is was very very small. Even a slight change in head/seat position caused a significant change in the size, shape and depth of the sound stage.

With this system it is exactly the same which proves two things to me: 1) What I was hearing was real and is reproducible and 2) Is more than likely a room dynamic which proves to an inexperienced audiophile that room dynamics are real. 

I have no intention of pursuing room dynamics at the cabin. It just is not a big enough issue with that system in that place, and my wife would not be happy......but it would be very interesting from an educational standpoint since there is a problem that I can hear and duplicate............which means that there would be testable solutions that I could apply.

Down at the cabin now. Just finished soldering new tiny little bulbs into my old Toshiba SA-2500 and they all worked! The old unit looks like new again. 

My my wife is sitting beside me and we are listening to Mark Knopler’s Get Lucky on CD and I’m totally satisfied with the SQ from this low end system. Tomorrow we’ll listen to The Rock and Roll Beach show on WRBK FM radio. She likes beach music. Life is good.
