Thiel Owners
@jafant thanks! To be clear, I have the small 0.5 and not the big 5 model, nevertheless they are unbelievable. After so many amplifiers it was the Kinki Studio combo that could show what these little Thiel can do! …also, they are 25+ years speakers that look and sound like new! |
audiofilo123 - the 'funny' part about your Copland amp comment is that Thiel speakers require current-source power rather than the ubiquitous voltage sources. An amp that will drive a Thiel, including your little CS.5s, should double its 8 ohm power rating into 4 ohms and at least 1.5x its 4 ohm rating into 2 ohms. The Copland might do well with higher impedance speakers, but not have the current delivery capability that your Thiels require. Frustrating? Maddening? Yes. Solvable? Yes. |
Based on your feedback, am looking around in the area for a possible addition to my gear, that of a power amp that suits the 1.6's. So far I have found: Hafler Trans Nova 9505 and a Yamaha M80. Both advertised at $1k and reported to be in great shape functionally and cosmetically. Still searching...

@tomthiel you are probably right… although the Copland, despite not doubling the power at half the impedance, it is a amplifier designed for tough loads. …the CSA70 is a distinct, standalone amp in the range, capable of delivering 2x90W/8ohm and 2x140W/4ohm with sufficient headroom to sustain peaks of 110W, 206W, 352W and a full 475W (21.8A) into 8, 4, 2 and 1ohm loads, respectively [see Graph 1, below]. Add to this fine load tolerance a usefully low 0.01-0.07ohm output impedance and response that's flat to –0.3dB from 1Hz-20kHz (and –1.9dB/100kHz). Also the LRS+ are quite demanding, very evident after some listening test with very capable amps, but the Copland finally showed a very firm grip and sure footed performance. But in the end it was the Kinki Studio combo that revealed everything (!) about the CS.5 capabilities. |
