Very much interested in this one, but not quite understand what app to use with it ? Wanna access Spotify and Tidal Masters, or perhaps MQA. |

.7's in for review
Quote:
I read in stereophile that INT-60 made .7 sounded too rounded and soft. Also read that XA200.8 made Wilson Alexia sounded loose in the bass. But it sure sounded sweet and musical. Quite interested in Ma5300 too, but then I will need areasonably good streamer to connect to it, may be Node 2i, SoTM 200 Neo, Cambridge CXNV2 or Azure 851N Last edited by TOGA; 11-30-2020 at 10:09 PM. |

The INT-60 is not Class A, but Class AB. The last sentence in HR's Stereophile review is, "Despite my dashed expectations, the INT-60 was still the best amp I've used with the Magnepan .7s."
HR also did the Pass INT-25 and XA-25 reviews. He owns both of them and his XA-25 review includes using with the .7 Maggies. Informative to read all three for comparison. Remember, reviewers pick the smallest of nits and wish to tell all. But, that he kept the INT-25 & XA-25 tells you something.

Yes I loved Class A, I had XA160.5 before with Revel Salon2.
Then not long ago I had Gryphon Mephisto with my Magico. It was really a magic in class A sound. For the new .7 of mine. These will be in a second room with Mainly will play TV sound from optical output or HDMI ARC, mostly will be NETFLIX and YOUTUBE. Then it will be played Spotify streaming. It is not gonna be much of an audiophile use at all. First choices will be one piece system. NAD M33 < which I am not sure of its class D nature, but love the interface. HEGEL H390 < good, but not really Made in Norway Gold Note IS-1000D < not report power in 4 ohm load, which is suspicious. The the second options will be separate streamers (that can do Spotify, Tidal Master(MQA). + conventional integrated amp like INT-25, MA5300,K300i. Not sure NODE 2i or Cambridge CXN V2 is good enough to show quality of Maggie when playing music. For now HEGEL H390 is number one for me. Toga |

Ok, I got the amp.
KRELL K300i. Very powerful and have a sweet Class A like Sound. Using loan Cardas for now, must find own cables next. May be Kimber or Transparent. Thanks or all advises. TOGA |

Oh no. Driving .7 at fairly loud volume caused the Krell to have Over Temp shut down. Messaged a high 81 degree C.
On display after shutdown. This Maggie must be very current hungry. Toga. |

I measured the Krell K-300i using my Audio Precision SYS2722 system (see the January 2008 "As We See It"). I usually precondition amplifiers by running them at one- third power into 8 ohms for an hour. The Krell almost made it, turning itself off after 55 minutes, with the front-panel display showing the message "Over temperature left channel." The top panel over the heatsinks was hot, at 142.8°F (61.6°C), but cooler over the transformer at 113.1°F (45.1°C). This is a tough test for an amplifier with a class-AB output stage, as one-third power results in the maximum dissipation in the output devices. The Krell has just sufficient heatsinking for its power rating but should be given plenty of space for ventilation. |

Thank you, I read this before but never imagined the little .7 would taxed K300i so easily. I think the current draw was so high causing that the iBias logic pumping high Class A juice than most other speakers. I did put K300i in a cabinet, with fully open front and back and 2 inches above and beside it, this met requirement regarding ventilation. I noticed a small heatsink for such a power with highly biased designed too. I hope small USB fans to draw cool air in from front and exhaust out on back of cabinet will help. Toga |

And it was 81c at shutting down which is quite high. I measured heatsink temp of my Gryphon Mephisto and Pass XA160.5 at only around 55c in open space driving Magico and Salon2. |
