2 Questions?

It has been pointed out to me by some posters here, that generally higher-end speakers are not so forgiving with poorly recorded music much of what seems to be 70 - 80's era rock.

Room treatments aside (and without cutting holes in my walls to vent my speakers outside as some have suggested).
I am looking for some advice from others about what speakers have worked well with this situation?

Currently running  Roon Nucleus through a W4S 2v2SE Dac tethered to CODA CSiB V1 configuration  
(150 w @ 8 ohm) integrated amp.  $3,000 ceiling, give or take.

Second question: Is there a decent quality speaker switch that I could hook up to my amp to simply toggle between two sets of speakers? My amp has 2 speaker outputs on the back but no A/B switch to change from one set of speakers to the other.

I see there inexpensive switches offered that have limited power ratings (eg: 100 watts per channel). Are these sufficient for doing the job? Will these switches have a negative effect on sound quality? Thanks.
Hey! No, I've never worked in home audio.  I used to work in motion picture sound though. :) Now I work in cloud based IT.

I like Monitor Audio because they are neutral and laid back and a good value. I had the Silver 6, now have a pair of slim lines in my bedroom.  My personal speakers are custom made, and if you have followed any of my blog postings you'd see links to them and their design.

Here's a good article on how the Loki works, it may help you understand what the you are doing with Roon:


I also recommend custom speakers from Fritz a lot. :) I’ve met him, and we chat on the phone, but I have no financial interest in his company. Not even a beer.

We just both like the same parts, and I find he's undercharging for his speakers a great deal, so we hit it off.
Great advice, thanks Eric, I'll bone up on this soon as I can.

I saw a set of brand new Golds for 1/2 price and was thinkin'...
Buy a decent subwoofer, I prefer a sealed enclosure like the SVS line starting with SB. I think the 2000 series is on sale now. You can turn it on and off as needed. I also have bought some used that work great for music like the older Yamaha YST line. I have two subs in my system to cover those lower frequencies better. Try this, I swear it will change your life. I even added an older Bose passive sub on my second system. I know Bose is a four letter word, but it worked great to round out some small bookshelves speakers. 
Thanks hshifi,
Oddly enough I was running a pair of Goldenear ForceField 4 (10") subs which I sold. It seems, at least for 2 channel listen, my Martin Logan Spires with a frequency response of  29–23,000 Hz ±3dB along with the 10" woofer already on board, produced more than sufficient base. I am considering downsizing to either bookshelf or smaller floor stander which may lead me back to subs?
