Integrated amp recommendation for B&W 805 D3 (Peachtree, Parasound, Hegel, Schiit?)


Hi, I just bought a pair of used B&W 805 D3 with the stand. I want to upgrade from my current Peachtree audio Decco 65, which sounds fine, but I am sure the B&W deserve better. I would like to spend around $2K for the amplification. I am OK buying used or refurbished. After reading a lot of reviews, I am considering another integrated amp, like the Peachtree Nova150 ($1800) or Nova 300 ($2500), Parasound Halo Integrated ($2500), Hegel H80 ($2000). Another possibility would be the Schiit Audio Ragnarok ($1700) and a separated DAC maybe the Schiit Audio Gungnir.

Any recommendation?

I also agree with the above Forum Opinion. I used to be a regular poster their not anymore. I find the crowd too aggressive in pushing their agendas and marketing products. Specially the 20,000 Plus HT Equipment Threads. That Forum is also now run by a company for profit rather than by Audiophiles or those into Audio in general.

Stelo,

I've had B&W 804S for several years since they were the new thing. At the time I upgraded amplification I did some listening at audio stores carrying B&W and different amp brands. I really liked McIntosh. My final audition was with the 804S and a Mc system where we switched from MC252 (250W solid state) to MC275 (75W tubed). I preferred the MC275 and have had it since. It has enough power for the 804 so I imagine it also does for the 805.
There is a McIntosh integrated that has the same amp section as the MC275. Maybe you can get one used?
I ended up with a Peachtree Nova150, but I am craving a warmer sound so I am considering an integrated tube amp (and getting a separate DAC). Here is my short list: 1-Cronus Magnum II, 2-PrimaLuna Premium Integrated, or 3-Raven Audio Nighthawk MK2 Integrated. I am lucky to live close to Upscale Audio in La Verne CA, so I hope I can audition the PrimaLuna soon.
Follow your ears. All good choices. 

I'd pay attention to what is ahead of the integrated tube amps you are demoing...this may help focus your DAC choice.
