Well they've been on only 20 minutes and I'm more than happy with these Epos K1i speakers, I expect them to open up a bit but out of the box they sound great.
The clarity compared to the Sonos setup is a different league and a little bit of a shock to the system when I do an A/B comparison using Spotify Connect.
I've dialed down the treble a bit and bass up a smidge on the eq in the Bluesound app though I may turn that off if the speakers (or more likely ears) adjust over time.
I have to say the remote control learning of the Powernode is bloody brilliant and can now totally control music playback from my TV remote which is genius. I've programmed the volume up and down to the channel up and down buttons on the remote to avoid changing the Beam audio level, works a treat.
Thanks
@Paul7777x for the heads-up on these, whilst I've not got much to really compare them with (other than from my distant memory) these were a great find and I don't honestly think I could have done much better for the price.
They don't seem to need a lot of power to drive them and sound really good at lowish volumes too which suits me down to the ground.
Even the wife doesn't hate them, at least she hasn't berated me too much though that might change though when she notices the Powersound box and I have to come clean about additional costs!
