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.

No affiliation, and I don’t promote anything here but rather just recommend products I truly believe are worth consideration by an OP.  I haven’t heard the new LSA speakers but am very impressed with the two respected guys who designed them from a clean sheet and that they reportedly targeted the Joseph Audio Pulsars and Perspectives — speakers I hold in very high regard — as a performance bogey but wanted to achieve that level of performance at a much more approachable price.  From the initial reviews I’ve read it seems they may have largely succeeded, which is why I recommend them and would strongly consider them myself if I was in the market for speakers.  That you can try them at home IMO is a huge plus.  Hope that answers your question. 
Hey Soix, the JA Pulsars really do seem to stand out as a superior product, but as you suggest, a little pricey to say the least.
The Statement's do look interesting though.
I was wondering if you were aware of this product at all:

His Tribeca-001's seem to have some good reviews (the white one, second picture down). 
Supposedly he is going to change the Dayton woofers for Eton Symphony's which is suppose to offer a huge SQ improvement?
