Amp Recommendations for High End Horn Speakers

Of course not. DC blockers reduce the audible hum from the transformer core saturation, not through onto the amp. Of you hear hum through the speakers, you need a better amp power supply.
No hiss? I have that A07 running some JBL Control X in a casual listening setup, seems to work great.

Hey there,
My Cairn 4807 just died. So there was Always this ground Loop Problem with it and now the Fuses burnt through and it wont Turn on.
I tried replacing the Fuses, but the AMP Turns on an instantly Kills the Fuses.
Is it possible that the Transformator is Bad?
Would explain also the hum
I really miss the phono pre of this AMP
Thank you
Florian

It's possible that the transformer is faulty, but I think it's much more likely that the bridge rectifier has has failed. You can test the transformer by unplugging it's secondary from the PCB, then powering it on: If the fuse doesn't blow, then your transformer isn't at fault.

Hi... Regarding low power amplifiers for your efficient speakers, have you considered any of the First-Watt amps ? Of course, they are notably more expensive than those mentioned so far that I've seen in this thread. I have the SIT-2 (10WPC/8-ohms) with my 94 db speakers and soon to have 106 db speakers, and this amp is the best sounding solid state amp I've ever heard on my system.
Pretty ****** at looking this distortion/power graph......
"The sound is fast but very smooth, with a very organic, musical character".
ROTFL organic sound .

I can certainly see the distortion curve. The real proof though is in the listening. The other descriptions of the SIT-2 in the First-Watt website match my listening experiences with this amp very closely. Interestingly also that the SIT devise itself doesn't hard-clip like other solid-state devices. I'm new to this website. What does your statement "ROTFL" actually stand for ? Thanks !

I'm not an EE but I know this:
An electronic color code or electronic colour code (see spelling differences) is used to indicate the values or ratings of electronic components, usually for resistors, but also for capacitors, inductors, diodes and others. A separate code, the 25-pair color code, is used to identify wires in some telecommunications cables. Different codes are used for wire leads on devices such as transformers or in building wiring.
Electronic color code - Wikipedia
Resistor Color Code Calculator and Chart—4 Band, 5 Band, or 6 Band Resistors - Engineering Calculators & Tools
A handy all-in-one tool for reading resistor color code values for a 4 band resistor, 5 band resistor, or 6 band resistor.
You have a blurry picture, so I can't see the colors, but google around: resistor color code and many links will appear.
