Which integrated amp?

Hi all,

I need help. I am trying to decide between the following integrated amps:

Exposure 2010s
Unison Research - Unico Primo
Vincent SV 236MK II
Musical Fidelity M3i

I have included below a list of my current gear. Any suggestions and/or advice would be most welcomed as I am having trouble making up my mind. I was trying to keep things under a grand, but have since upped my budget to around $2000. Please check out my list to match an amp to my current gear, and get back to me with any thoughts, suggestions, recommendations, etc.

Thanks so much!

I currently run the turntable through a phono amp connected to the auxiliary 1 input and a USB DAC connects to the auxiliary 2 input. I am also running a line out from the aux 1 that I connect to my laptop with an RCA to mini so I can record/rip vinyl. Any new amp I purchase would need to have a line out that I could use to rip vinyl. So, keep that in mind. I mostly listen to Rock music and a bit of Jazz with occasional Funk and Soul thrown into the mix at times. I also would need a line (or pre?) out to connect a headphone amp, as my current amp has a headphone jack, and the amps listed above do not.

Also, I am using basic thick black rubber encased RCA interconnect cables. Not sure what brand they are. They are a step (or a few steps above) the basic cheap RCA cables, anyway. I know that cables can make a difference in sound quality, but my budget will not allow for expensive cabling (at this time). Any suggestions on relatively inexpensive but high quality cables would also be appreciated.

Thanks again for your time!

With the type of music you prefer and with the aggressive treble of the B&W CM series the Vincent appears to be the best fit. I think the Unison could be to soft for rock/funk, MF could accentuate the B&W flaws, and the Exposure might be underpowered.
Other "used" options...
Quad 909/99
AVI-Laboratory Series Intergrated
Electrocompient-ECI 5
If you ever consider upgrading to the CM 8/9 you won't have to upgrade your amp with the Vincent or the suggested used amps.

You really need to upgrade your cables. Google Blue Jeans Cable....very good and cheap.
A 3 ft. IC is about $35.00....Belden low capacitance

You need to check out the Harman Kardon HK990, it is one fantastic integrated and has all you would ever need on it.

I have owned the Vincent and the Exposure. The Vincent is very nice but in my system with my chair, beer, cable, speakers and so on I found it ever so slightly thin sounding but pretty good overall. The Exposure is something else. it is stunning what comes out of that little box. I had a Creek Destiny here one on one and the Creek was very clean and detailed but the expousre just plain sounds like music and makes everything else sound mechanical. I had an Anthem 225 here and the Exposure
sounded more powerfull and more musical
Now I have heard many things and am picky but not rich. I also worked in the audio biz but I still had a hard time believing what I was hearing so I called a dealer out of state who carried both the Creek and Exposure and told him what I heard. He laughed and said they see that all the time with customers. He used the term organic to describe the 2010S. It reminds me of an NAD 3020 upgraded.

FYI I moved us to the 2010S2. it is warmer with more bass but I think I may have liked the original better. Had to sell to pay the bills.

Hi all,

Thanks for the input. I will take all your considerations into account.

Geph0007: do you agree with Dayglow, that the Exposure may not be enough power if I decide to upgrade my speakers in the future? Might the Anthem 225 be needed, and Asa a result a "better" choice, or...do I really also just need to listen to each of them? I am gonna try and do just that soon. There is shop by me that carries both of them, so at least I can do an in-store listen.

Let me know your thoughts. Thanks!
