Moving from stereo to surround

Hello all,

Currently I’m listening to stereo on a pair of KEF Q350 speakers with a Marantz PM6005 and NA6005 as the amp and streamer. I’m looking to upgrade a to 5.1 setup with floor-standing speakers as the fronts and a Denon AVR most likely x3700h.

Would you recommend keeping the Marantz units as the music setup and using the Denon for HT duties or would I get better sound from the Denon and would I be better off trading in my current setup?

Any advice you can give me will be greatly appreciated.

Some Suggestions

Don't know if your amp will have enough power for the future. Don't know what your budget is for all at once or instages. I wrote some ideas in a thread before this in error that may still be some help to you. Because you already have Kef, you might want to stick with that for consistent tonal quality in your mains. You could start by adding an SVS SB-2000 sub if you can get one or a SVS SB 1000pro. Audiophiles are totally right about having a sealed sub. It is much better for music just get one with enough oomph for movies. Next step would be a decent center speaker. Kef could help you there too but probably not inexpensive. If you've got the height and want to save money, the Polk S30 could work well. Do some critical listening with as many of yur considered pieces as you can.

Center Speaker Challenges

The size of a center speaker (especially height) is a factor as well as where you put it. Open space or in and under a tv stand top. If in a cabinet how will that acoustically behave? In those circumstances passive radiators or built in subs are not your friend in an enclosure. Many centers are dogsquat below 70hz as they try to hide behind improving "dialogue." Getting to 50hz bass (to blend well with your mains) starts to add up in cost. While many other center speakers perform better on poaer I have found the Polk CS10 to perform surprisingly well and I'd have the Polk S30 but it is too tall and too wide for my cabinet. CS20 was a very good center as well but no longer made and too big for my limitaions.

If the OP needs a center

If the OP needs a center (andI believe one does), another Q350 would be ideal and superior to any of those Polks. Another pair of Q350s for surrounds, too.

Thank you

Thank you for the feedback. I will check out the SVS Subs soon. What is your take on the cylindrical models? In terms of speakers, I've narrowed it down to Kef Q series or Q Acoustics 3000i series.

Does anyone here have some advice about keeping the amp/networkplayer for music or would a receiver suffice for both home theatre and music duties?

Regardless of anyone's advice, get the AVR and, then, decide for yourself.

SVS Subwoofers

Trying to carefully and respectfully be some help to others. We’ll depth charge the word Polk going forward. I’ve not heard the cylindrical sealed SVS subs but all SVS subs have reviewed well in many reviews. JL Audio is even better (not heard by me) but more expensive. Some listeners like the cylinder style for space efficiency but may pose a challenge for children and pets. The SB-2000 that I use is a sealed approximately 14 inch square cube and tastefully augments music while sufficiently pressurizing a room for home theater. One SVS strength is building capable subs in a relatively compact package. I would suggest studying the brand new SB-2000 Pro that just came out as it has a Control app that takes time and guesswork out fine tuning the sub to your liking without frequently getting behind it to adjust settings.

I know that a number of audiophiles aren’t keen on subwoofers but carefully applied they can make worthwhile contributions. I use Pure Direct a lot for usb and CD playback but sometimes listen to 2.1 on Direct for certain types of music. You should like the contributions of a sub for music with orchestral majesty such as Aaron Copland’s Fanfare For The Common Man comes to mind. There is a lot of musical information below the 63-64 hz of the Kef 350. Some people like to save money with a good sub taking up the slack as it is less expensive then a full range pair of tower speakers that can play down to 35hz.

Expanding to 5.1 channel sound whether for surround music or/and home theater should be an exciting journey for you and the speakers you are thinking of are a great place to explore. Couldn’t tell you as much about the streamer other then it seems like something to keep. The Denon 3700 should be a good hub for tying all this together. Not as good as separates but separates for 5.1 channel sound can get fairly pricey fairly fast. Down the road it is always possible to add an onboard amp (or 3 channel amp as Kalman Rubinson has done.) If you would like to og that route in the future and use your receiver as a quasi-preamp then make sure the Denon you are thinking of can do that. The benefit is this approach is the receiver doing less work while still providing onboard channels for the surround (and maybe the
