I'm a few months into my Sonos setup, and absolutely love it. Yes, my first (two!) cars didn't cost this much, but I consider it one of the best investments I've ever made. I have 5 zones with a mix of Play:5 and Play:3 speakers, and also using my own speakers -- which is where the trouble is.
In my living room, I have a Connect:Amp hooked up to a pair of Polk RTiA1 speakers (http://www.polkaudio.com/products/rtia1). The sound is... disappointing. I should clarify: The sound is spectacular, certainly more sophisticated than from my Play:3 or Play:5 speakers, which already sound great. But it doesn't seem as "powerful" as it should be, for lack of a better word.
For one thing, with all zones on the same volume setting, my living room speakers are noticeably quieter than the others. I have to turn up the volume in that room by perhaps 20% to equal the volume being played elsewhere. Also, with the volume set somewhere around 5% maybe, there's not really any music coming out of the speakers at all, while my Play:3s and Play:5s are still audible.
And second, it just feels like the overall power isn't that impressive. It's uncomfortable to stand in front of my Play:5 with the volume even close to maxed out, but not so with my Connect:Amp/Polk setup. Turning the volume all the way up is indeed pretty loud, but not the blast I was expecting. Not that I'm aiming for a setup that makes my ears bleed... Just making the point.
I hooked some other speakers up to the Connect:Amp and had the same issue. I don't think the Polks are the problem, and like I said, they do sound amazing for what they put out. (They are also gorgeous!)
What I'm struggling with is whether to keep this setup. Maybe my expectations were too high, maybe I've got something screwed up on the technical side, I don't know. This is by far my most expensive Sonos room, though... About $825 including the Amp ($500) and speakers ($325). I'm wondering if a $600 pair of Play 3's would sound the same or better.
Anyway, eager for any advice anyone has to offer.

Never was a truer observation made, NoBob! I bet more than a few Sonos users encounter this unfortunate reality.
I just have the two pair of speakers, and each pair have their own volume knob. On the knob there is a switch where I can select 1x,2x,3x or 4x. I have those set to 1x since one pair of speakers are wired to it. Does that sound correct?
Thanks Again for all the help.
Your options for higher output then would be replacing the speakers with higher efficiency units, replacing the Connect:Amp with a Connect and a much more powerful amplifier, or both, or separating the two zones and adding another Connect:Amp, eliminating the switcher (unless it does other rooms as well).
Time to evaluate just what "loud" is 🙂
I recommend strapping the two volume controls at 2x and eliminating the box.
One piece of data that would be useful would be to turn OFF one of the speaker pairs and turn OFF the selector box's protection. Is the room loud enough now? If not, you'll need more amplifier power, more efficient speakers, or an "attitude" adjustment.
I was kind of thinking about this as well. This is the way a custom installer suggested I set it up but I dont know why I need a selector.
If I elimate the selector and set both volume knobs to 2x, then I will have two 14-2 wires that I need to connect to the C:A. Is there any problem with this?
Thank you both for your input.
Two #14-2 will fit. With some practice, skill, and luck, two #12-2 will fit too.
In nature, nothing is free. Part of the physics of the 2x impedance conversion is a drop in overall output level. The level drop is the "cost" of the impedance conversion. By the way, unlike the speaker selector "protection", which inserts a resistor, the transformers are very efficient and don't waste much energy. The resistor could easily waste half of the energy.
I guess my expectations are too high.
Thanks for all the advice.
Have you set the Connect 'Line-Out Level' to 'Fixed' (equivalent to 100%)?
But such differences also exist across Sonos play unit models, and have to be dealt with in similar ways. Your Connect is almost certainly working as designed, just keep the slider at a higher level for the same level for the Sony amp for obtaining the same sound levels as from other sources. One thing to try that is not expensive is to switch the cables to another commodity RCA pair - not to expensive brand name exotica.
There are some pre amps in the market, like the Quad 99, that have inputs whose sensitivity level can be changed to handle precisely these situations, but the 99 is too expensive to be added as a solution here. Just to point out that a solution does exist that is worth it only if all its other features are needed.
Settings->Room Settings->(Connect room name)->Line-in Settings.
This is from the Windows controller, but roughly the same applies to the other controller versions.
