Is bi amping worth it ?

OP,

The Cambridge exn 100 is a budget streamer. You can easily assemble a streamer / DAC combo that sounds the same or much better than the McIntosh mvp 871. It is a question of careful choice and investment. In today’s world it is worth working on making streaming your best sounding option. 

I would abandon the bi-amping for now and concentrate on getting your components sorted out. You want synergistic and an equally capable streamer, DAC, Preamp and amp. Assuming you are happy with your speakers. Then you work on cables and power cords. If you make your decisions based on the sound quality of the components, I have ended up investing about streamer = DAC = Preamp = Amp < speakers. 

My vinyl = CD = Streaming... except where streaming is high resolution... then streaming wins. This is here now and the future... streaming...so  I’d recommend getting that right.

I'm glad you got to hear AR9's way back when. I also heard Klipschorns many years ago and they did sound very good. It is a different kind of quality. I just read about and heard a discussion about their origin and Mr Klipsch. They began shortly after WWII and his story is quite entertaining. He even had something to say about early AR's, citing bullshit which became a bit of his mantra. He was quite a character. 

Anyway, 2 ohm would make me nervous but there are many here far more qualified than myself to answer that. There are builders and designers here. I am just an avid listener, who is still not deaf after nearly 73 years of listening to rather loud music...........within reason. 

@ghdprentice may be onto something. I know diddly about streaming and I don't know your primary source. I don't stream and I possibly never will. It is as important to me as having an HT system..........not at all. I'm just an old stereo geek. Check his sytem/systems out. He knows a thing or two as do a great number of the experts here. They have likely seen and heard it all.

Call me crazy but I consider my REL Stentor III to be my bi-amping solution. I use the Voxativ AC-1.6 full range drivers in a baffle, and I run a second line from my amp's speaker taps to the REL powered sub. I also used the REL when I was driving Wilson Sophia and Daedalus Ulysses V2. Why? They didn't need to bass support, but the sound was more open and transparent, which I attributed to using a separate amplifier for the lowest frequencies. 

Yes.

Not worth it. 
 

get a Schiit Loki Max for tone control to adjust the bass punch higher by a smidge. Then get a subwoofer or 2.
