Preamp for BA-90

I see that there's a BA-90 amp on Ebay at the moment, but I can't find any information about what preamp was made to go with it. There's no listing for a matching preamp anywhere that I can find.

So what did Sansui have in mind with the BA-60 to BA-150 series of amps if they didn't make preamps for them as they did for their other lines of amps?

No BA-90 listed in Orion.
There are the B-55 & B-77 and matching preamps C-55 & C-77. It would seem there would also be a C-90.
I looks like they are from the very early 1980s.

It was meant to feed the BA-90 from any amps preout or using a crossover unit as CD-5 for a tri-amp system

So the BA-xx amps weren't ever meant to be part of a matched system like all the other series, but as orphans to be used as sort of a catch-all, "wherever you want it" kind of thing?

I don't know how old you are Stene, but I would like to hear from people who actually bought these brand new and actually used them in a system. It would be fun to know how they were actually used by their new purchasers back then.

Here's my thought: I was thinking that it would be a great and cheap way to build a "system" around an IPOD type MP3 player.

Imagine the BA-90 pushing a pair of Bose 301 Series III speakers, and a Cowen iAudio X5L MP3 player plugged into the input of the BA-90.
The X5L is a "full service" device that not only stores hundreds of hours worth of albums, but it also has an FM tuner, and it has lots of extra sound tweaking effects (like a preamp would have... but more and better).
I already use my X5L through my living room system and it sounds as good as any CD that I played on the system before they got ripped to the X5L (I rip to OGG Q6), so I already know how good the X5L sounds going through a hi-end system.

The BA-90/Bose301/X5L would make a great "garage system", it seems to me.

Hi Mark
Yes I'm old enough to have bought these BA amps new in quantities but I never used them, I was the importer/distributor in my country.
There are more in the series. BA-60 WPC 20W/8 ohms, BA-90 WPC 28/8 ohms, BA-100 WPC 30/8 ohms and BA-150 WPC 45/8 ohms where BA-100 and BA-150 both have two inputs.

The way to use a Basic Amp is up to the user. Your idea is one another three you can see at the pics

Hmmm. It looks like a Basic Amp is a pretty handy thing to have laying around for when one wants to get more creative. :scratch2:

I like what I have in mind with the MP3 player because I get a kick out of the idea of adapting "old" technology (Basic Amp) to something it was never even dreamed of being used for (amp for an MP3 player) and ending up with a "system" that is incredibly useful. :thmbsp:
