This is my current primary Music/HT system. I am probably split 50/50 in usage. Just discovered vinyl and how wonderful they sound on the Maggies.
Until recently, my biggest gripe was the lack of a deep, bass foundation. I was previously using a single V2W for both HT and music. It did a good job but I wanted more. The addition of a dedicated 2Wq for each Maggie has far exceeded my expectations.
02/14/04 - Just replaced the McCormack .5 REV A for the MG 3.6R, with 2 Rowland 201 monos. The amps are still breaking in but the system is much more dynamic with a much larger sound stage.
System edited: I finally added 2 dedicated 20amp circuits with Shunyata Venom outlets. Replaced the Python with the Alpha on the RGPC1200s. Per my dealer, I had the 501s plugged directly into the wall. I found that the highs were ocassionally harsh. I currently have the amps in the RGPC1200 where the highs are smooth. Compared to the Python, the Anaconda has a much blacker background.
Drubin - I only have experience with Shunyata (Snakebite, Sidewinder, Black Mamba, King Cobra, Taipan, Python). I have never used the stock cord on the 201//501. The Taipans make the Rowland very dynamic and energetic. The Taipans work well on the amps but makes the CasaNova or Concerto too forward. I currently have the amps plugged into the RGPC1200 which is powered by a Python Alpha. This makes a smooth combination. I have been itching to upgrade to the Anaconda Alpha. Before the Python Alpha, I had a Taipan on the RGPC. This was a dynamic combo but the Python is less harsh.
I recently had dedicated 20amp circuits with Shunyata Venom outlets installed. I tried the amps directly into the outlet but did not like the sound at the high end which was sometimes harsh. The RGPC smooths the top end without hurting the dynamics.
