Hi Jtomes,
Any progress on your decision on an amp for your Thiels?

Anyone used the Rogue M-180's to driveThiel 2.7's
I just replaced my venerable 3.5's after 21 years and I am going to splurge on new amplification. I know Thiel uses SS as reference amps (Krell and Bryston) but I am jazz and classical guy and have always leaned toward tubes. Thiels are ineffecient and at 4 ohms I am concerned that they will play loud enough. I do not play rock concert levels but I do like to crank them up once in awhile.

Telescope_trade, thanks for catching my error, looks like dyslexia got the best of me. Nevertheless, looking at the Thiel website, the CS2.7 has a nominal 4 ohm rating with a minimum of 2.4 ohms, even lower than the older 7.2. Considering the statement in the M-180 review, it still looks like the amp/speaker match will not be good. |
The impedance graph for the 2.7 shows it dropping well below the 4 ohm nominal rating. Take a look here, http://www.stereophile.com/content/thiel-cs72-loudspeaker-measurements Reading the last line in this review on the M-180 suggests using it with a speaker load that does not drop below the nominal rating, http://www.stereophile.com/content/rogue-audio-m-180-monoblock-power-amplifier-measurements It appears that this will not be a good match, and I'm guessing the speaker is just not tube friendly, might be best to use SS. |
I just bought a new Peachtree Nova 220 amp and Nova pre amp and it seems to be a superb match so far for my new Thiel 2.7's. I only have about 25 hrs on them and about 250 hrs on the Thiels and also just added new speaker cables & PC's. So all of it is new but I am very happy with what I am hearing already, simply outstanding! Sorry, no experience with the Rogue's. |
