I believe that I've remedied my problem with the help of Sumiko. Rowland amps input- pin configuration are different from industry standard. When auditioning these amps, I did not have a balanced cables to use since my preamp, uses dual RCA on its balanced output. I had to use an RCA to XLR adapter. Because of this, the REL did not see the positive signal because of Rowland pin configuration. Unfortunately, I was not able to hear the sub with the Rowlands because I promised the dealer that Id get the amps back in their possession by today. Im confident enough with Sumiko's remedy and ordered the amps. Sumiko contacted a dealer who has a pair of 201's running with a Stadium III and came up with the solution. The dealer told Sumiko that once the pins are switched, the sub should work perfectly with the amps.
To answer Dublins question on how the 201s sounded with my Thiels. When I first heard the amps in the dealers showroom, I was very unimpressed. He had them running to a pair of Focal.JMlabs Alto Utopia Bes, a Simaudio Moon preamp and Simaudio Moon Eclipse CD player through the Rowland 201s. After doing a bit of research and urging from a friend who stated that the synergy of the 201s with my Rowland Coherence preamp needs to be auditioned. What a pleasant surprise when I did this. This preamp-amp combo simply made my Thiels sing. My Parasound 2200 and Conrad Johnson tubes are the only other amps Ive had in my system. The Parasound got it done with a nice bass and nice laid back sound. Maybe a bit too laid back for some. The CJ MV60 was wonderful with more non demanding music and moderate at best volume levels. The CJ improved my system and made the music sound fantastic with great highs and a wonderful midrange. If Id have gone this route, Id need a pair of MV60s or a Premier 140 because of lack of bass or weight to the presentation. The Rowlands just took my system to a different level. To put it simply, the 201s didnt make my system sound good, it made the music sound real. Crystal clear highs, a realistic midrange, and a decent bottom end. As earlier stated, I was not able to audition the REL with the 201s.
I feel that some will be very satisfied with the Thiel 22s 2.3s or 2.4s without a sub. I did not have a sub in with my Thiels for eight years. I only added a sub because of home theater. I thought that if was going to purchase a sub for HT, Id might as well get one they will add something to my music. Now that Ive had a great sub in my system for a couple of years, I dont think I could every live without one. It just adds so much to the music. Now the crazy thing; all this took place with a RCA to XLR adapter and negative and positive pins reversed. I cant wait to hear my system when I receive my 201s with the correct cables and REL sub.
