Question about Bose 901 VI Main / Stereo Speaker
Bose 901 speakers are designed to use with the Bose equaliser patched between the pre-amplifier out and power-amplifier in of your receiver. Having said that, Bose did not invent EQ, neither is EQ a mystical process. Not sure which series 901s you are talking about, but I would definitely be experimenting with the built-in EQ supplied with your Sony DA5800 ES. The manual says you have +/- 10 dB of adjustment for treble and bass for each of the surround channels. That is not really adequate in my opinion, not only would I be seeking +/- 15 dB, but I would also like to be able to apply those adjustments at frequencies chosen by me, not just 'treble' and 'bass' To use the Bose EQ, it needs to be patched between a preamp output and power amp input. The Sony DA5800 ES has preamp outputs, so you could use these (Note that the built-in EQ is disabled when using these outputs) In this case you could either feed the signals back into the Sony (post Bose EQ) perhaps using a different 'Zone'. As an alternative option, you could power your 901's with a stand-alone two channel power amplifier. Then you get the full benefit of the Bose EQ as well as the surround sound from your Sony (front L+R speakers off) It all sounds like a lot of fun. Happy listening! Cheers, Don.

SOURCE: bose 901 v1 adding a amplifier
You may connect an additional amplifier to the Rec Out or Line Out from your existing receiver.
Please note the Bose 901 equalizer can be used to connect to one amplifier only.
Do let me know if you have any further questions.

I contacted the Customer support folks at Bose. Here is what they said:
With a stereo receiver, the equalizer is run through the tape monitor section in the back of the receiver. The receiver's tape monitor output, left and right, runs to the amp input section of the equalizer, left and right. Then the amp output section of the equalizer, left and right, runs to the receiver's tape monitor input section. With a surround sound, home theater, type of receiver, the theory is the same, but the connection is through the preamp-out/ main amp-in section of the receiver. Not all receivers have this feature. Most, in fact, do not. Check the back of the receiver. There would be a connection made by two U-shaped clips. The plugs would be pulled out. Then connect from the preamp-out to the equalizer's amp input section; and from the equalizer's amp output section to the main amp-in. This effectively isolates the equalizer so that it is not affecting the other speakers in the system or the receiver's surround processing. Attached is a current list of known 901-home theater compatible receivers:

I have the list in a pdf document but do not see a way to attach it.

The solution is simple and cheaper than you think.
The analog 5.1, 6.1, 7.1 outputs on your receiver should be active even with digital inputs that you want to hear. Your receiver turns everything it processes into analog output just before the speakers anyway so there's no loss of access to multichannel sound this way.
What I did was to buy a separate amp for the 901's and feed the Front L&R analog audio out to the EQ which is directly in front of the amp. The Active EQ is only for the 901's which don't have woofers or tweeters so Bose flattened out its final response electronically with some serious boosting at both ends. Having it in line with any other speakers would feed them a grossly over-compensated signal.
Your receiver will drive the rest of the speakers.
This is the cheapest way to have your 901's and hear them, too. Since the 901's are really efficient you don't have to buy a big amp that would heat the room. I'm using a separate Carver amp with 2x100w for mine.
