I am looking forward to upgrade my speaker system from SL3. I have a room which measures 25' by 13'. Currently, my speakers are 6' from the back wall and 2' from the side wall. My listening position is 7' from the speakers. I am very happy in terms of imaging and the overall quality. I am using Plinius SA-102 AMP( 200 Watts in 4 Ohms load), Sonic Frontier's Line -1 preamp (Siemens NOS Tubes) and Wadia 861 CD player, DH LABS Q10 Biwire speaker cable and DH Labs Silver revelation Balanced IC. I listen to jazz mostly. I have an option for going for Magnepan 3.6R or ML'S Vantage/Summit. I think this will be my final investment on speakers. I will be moving to a place in future where there are lots of humidity and the room size will be similar. I look forward for any of your valuable advice.
