Help me power my Kappa 8.1's please!


I would like to Bi-amp these.  

Budget is a real thing (I just dropped about 3500 getting into vinyl)  I'm hoping to spend between 500-1000.

I would consider Vintage gear, but I despise spring clips.  I would prefer something NEW, but am open minded.  Has to look nice.  Blue lights a plus!  Can't I just have everything I want already lol!

Infinity Kappa 8.1
6 ohms
40-300 watts RMS
89dB 2.8V/1 meter 

I've been looking at modern integrated's but the low impedance has me confused about what will be compatible...

Thanks and Happy Friday!

I just read a review of the Anthem on digitaltrends and if it sounds as good as they make it sound then I WANT ONE!  

With that much power, Bi-wiring should sound great right?  I was thinking Bi-amp but this would simplify things.
@tls49. Thanks, can you tell me more about going dual mono block setup?  Would i still need an integrated
amp?  

I have two inputs - one from computer via dragon fly red dac and one from TT via tube preamp...


As one member here said, "Bi-wiring may or may not make a difference, and if it makes a difference, it may or may not be better." Some speakers have actually been designed for Bi-wiring, but for the majority, it's just "audio fashion." Bi-amping done properly means you would need to bypass the speaker's internal crossover and use an external crossover. Keep it simple with one quality amp and a single run of speaker cable, you'll have less headaches and more enjoyment.

Here's a good read...  https://www.qacoustics.co.uk/blog/2016/06/08/bi-wiring-speakers-exploration-benefits/

I already have bi-wire speaker cables.  If nothing else, it's less resistance.  But I do hear a difference.  It's subtle.  

I noticed a much bigger difference when I wired my speakers in parallel (ch A to High Fr and ch B to Low Fr) on each speaker.  I did this with my cheap Sony 2 channel amp (100W per channel @ 8ohm) and ran A+B at moderate volume levels for a month or so before someone told me I was crazy to do that and so I stopped and went back to bi-wire.  Its a cheap amp though and it sounded WAY better so I'm thinking about doing it again!  There was more separation, and energy, especially through the midrange.  I don't know the internals of this specific amp but it made everything sound better.

This is why I want to bi-amp these speakers if I'm going to spend money on an upgrade...

Thanks @matt0404, will look into that one tonight... 

Any love for the Onkyo Integra A-8170 in the forum??  One came up locally on CL and it got me thinking.  For $250!?

Super sounding integrated amplifier. The amp is conservatively rated at 80 watts at 8 ohm per channel, and more than double at 4 ohms, and has lots of audio headroom. The amp will drive low impedance speaker loads without strain.

Power is rated at 80 w/ch continuous into 8 ohms, and dynamic power is 115 w/ch into 8 ohms, 170 w/ch into 4 ohms, and 224 w/ch into 2 ohms. Damping factor is 50, and harmonic distortion at rated power is 0.008%.


I bought a Yamaha S-801...  ($660 delivered - factory refurb)

it was always on my radar but the more i read and thought about my needs the more it rose to the top.

I’ll report back soon!
