Moved away from SS amps and went to a tube based system front and center is the Viva Solistino 845 SET IA rated at 18wpc of pure class A power. The Viva is driving the Daedalus Argos speakers with no problems it has plenty of slam, nuance, great sound stage and uncanny imaging. The DAC is a Lampizator Atlantic TRP, upgraded to include a VC, which is also tube based and adds richness to the sound of the system.
The server is the Aurender N-100H and I also like to spin CDs, from time to time, and have the Cambridge CXC transport. All cables are Cardas Cygnus and Pangea power cords.
Replaced the JL E-112;s with a pair of REL S/510's subs in an effort to get better integration with my main speakers, and I believe the REL's achieved this end. The subs with my speakers do sound very good.
I posted a mini review on Audio Circle which I described the difference between the Accuton vs the Scan Speak bass drivers...at least to me. Check it out and let me know if you have additional questions.
Yes, the sub been in the system since April. And yes it is a very nice addition. The sub was much easier to integrate than what I had expected and a welcome improvement on the lower end. Adding a second sub is a definite yes...hopefully by years end.
