Mcintosh MX170 2-Channel Sound


I am slowly building a home theater system and I am curious if I would need a stereo preamp if I use the Mcintosh MX170 processor.  Speakers are Sonus Faber Amati Traditions with D’Agostino amp.  Is the sound quality for stereo good enough from the MX170 or would I also need a preamp when listening to music?

You will need power amplifiers for base and height speakers.
How many channels ?McIntosh power amp. ?
Some people will find the sound very good for music using the processor only .
One power amp ( 3 Channels ) for the fronts and center speakers.

Others will hear a difference with a highend preamp connected to a
highend power amplifier for music.
The preamp must have a Home Theater Bypass.Whatever route you choose , select the right grears that pair well with your Sonus Faber Amati Traditions .

You may choose to have a dedicated   system for music. 

OP you're asking question you need to answer. Is the sound good enough for you? Does it sound good to you? Do you want to make it better for a reason or is money just burning a hole in your pocket? :-)

D' Agostino amp? How many channels are you currently running?
Does your Mac have a "Pure Stereo" selection?

I read up on your MX170. It doesn't say a WORD about two channel playback.. LOL I'm not quit understanding that BUT that is Mac.. I have a lot of Mac stuff.. Play through and a good Stereo Preamp will go a long ways..

Stick with Mac.. They just work together well.. C220-2700 or C47-52

Enjoy..
I have the D’Agostino classic 3 and it is powering the Amati’s and the Vox center channel.  Long term my plan is to get monoblocks for the Amati’s and have the classic 3 power the Vox and the rears.

I do not own the Mac yet, I have a Yamaha CX-A5100 and it needs to be upgraded.  So I was thinking about the MX170, but was also considering the Audio Research Ref6 preamp and keep the Yamaha for movies.  I am trying to get them both for a home demo so I can decide if the Audio Research really sounds that much better, if not then I will go with the Mac.  
My question was not very clear at all, sorry about that.  I was basically asking if I should get a stereo preamp to go with my Yamaha processor or skip the preamp and just get a much better processor (MX-170).  
Funny OP I have 2 MX110z, MX120 and a MX121. My preferred is the MX120, the only reason is the remote. The 110z will just whip the pants off in any of the 2 channel stuff. The 120 though.. a serious 2 channel stereo, it’s ALL Mac.. I’ve found a couple for under 1K.. C2500 and their C11-22 are pretty nice too.. Its just the remote thing.. BIG C20 fan here too.. Samra Touch..

2 speakers C2500
3 speakers MX120
more than 3 speakers MX121

I can take a 3.XX system, after 3 main speakers I get all mixed up.. AND I don’t watch HT UNLESS, the wife wants to hear a live recorded concert or something..

Besides I’m a tonnage guy when it comes to speakers.. BIGGER is better.. 3 speakers is 3/4 of a US ton 1500 lbs.  Add MB columns and subs, couple of tons pretty easy..

I'm trying to repurpose a pair of 12 CF 300 lb subs columns now into spring bass traps.. Maybe I'll just hang BASS sucking dingle berries inside..???

As a Mac and ARC owner ( MX119z and REF5se ) I think you will find the REF6 awesome ( yes I have heard many very modern Mac components ) but definitely listen to them both if at all possible....

the obscure “ Samra” reference is to I believe ( hello mech )
Mike Samra in Saginaw who modify gear , including my MC240 ) Mike is a quirky genius capable of wonders.

have fun, enjoy journey and the music

Thanks for the comments, and for explaining the Samra reference, I had no idea.

I currently have a 5.2, I have a sunfire amp powering Kef LS50’s for my rears at the moment.  I want to get a pair of full range, possibly SF Olympica III’s or something.  
I wish I could hear the MX170 in my set up while listening to music and compare it to a good preamp.  I am not sure how much better the MX170 will be in movies over my Yamaha but I am guessing a dedicated preamp will beat the MX170 in 2-channel enough to make me pick the preamp first.  
I think it is likely that a high end 2-channel preamp will still be better than the MX170.  While the MX170 is going to be a very excellent HT processor, it still uses op amps for all analog stages (both input and output stage).

I think the only HT Processor that I would consider being in the 2-channel analog preamp level is the Bryston SP3.  It uses their fully balanced and fully discrete analog stages for BOTH input stage and output stage.  That being said, it is my opinion that the DSP/DAC board is compromised and is not to the level of other devices (such as Krell, etc.).  The SP3 has just about the strongest and fullest bass I have ever heard from a processor, though.
