I'm running the LP140 Monos and am very satisfied. The series started with the 70 and the 140s and then for a period the 275s... all great amps with similar circuits. The new ART monos replaced the 275s as they would have been an overlap in the product line... but the 275s were and are terrific. As good as it gets south of the ARTs. I believe the 70/140 series was replaced by the current models to allow them to compete at a lower price point in this economy. Case work alone accounts for a significant amount of the cost... have you seen the new D'Agostino monos at $45K for instance. Beautiful, but half that price is cosmetics. If you like the power and that many tubes, make a deal on those amps your listening to. Also, inquire if they have had the factory mod to the input tube circuit. It makes the amp less sensitive to the absolute quality of that V1 driver tube. Bob Last edited by Coppy; 12-27-2011 at 06:05 PM. |

Welcome aboard, Regnad. Will be interested in your take on the 275's as you give them more of a workout.

I run the prem 8a's with the cj teflon upgrade.the BIG cj power amps are awesome!! the stk tubes are very very good. Personally I would stay with the same input tubes that cj use - you have plenty of time to tube roll if you want to later. The 6550's are more problamatic. the factory supplied Svet winghed C's are now hard to get and quite expensive - they sound wonderful. I use the current production Tung Sol 6550's and they are very good and a LOT cheaper - not sure if they are better that the Svet, but I don't hunger for a change any time soon. As Stephen said, there is the KT120's now - can't comment as I have not heard them. Personally I don't need any more bass, so these tubes are not a priority for me - but with 16 + 2 spare output tubes, it can get pricey no matter what. |

Thanks for the kind welcome.
I was using Parasound JC-1s and my speakers are inefficient so tubes are a problem. My dealer leant me the 275s and they work well but are power-hungry and hot and higher maintenance so I think I'll have to keep the JC-1s. I can't imagine the 275s sitting there when it's 110 here in So California. So, summer and winter amps? I'll have to see how good a price I can get. Thanks again for the advice and Happy New Year! |

Efficiency won't be an issue with 275 Wpc on tap, nor will tube reliability. It gets up to 110 inside your house in SoCal?

Thanks!
I have 82db current-hungry MBLs and, yes, my living room might reach 110 in summertime even with A/C with the 275s! |

Whew! I can see why you'd be concerned, then.
