Prima Luna Premium Pre


Hello,

How does The Prima Luna Prologue Premium Preamp compare to the larger tube companies like Audio Research, Conrad Johnson etc?

I was talking to a dealer who was really praising Prima Luna, their superior build quality and sound.

I am a bit skeptical as I don't have any knowledge of Prima Luna and I see they are a Chinese company.

Does anyone have experience with Prima Luna and how hey compare with the more established companies?

Thank You

The 57.5 db gain of your phono stage will raise the output of your cartridge by a factor of 750, so the 0.5 mv rated output of your cartridge under the standard cartridge test conditions will be raised to 0.375 volts. The peak levels of some recordings will be several times greater than those standard test conditions, but still the maximum output levels of many digital sources are likely to be significantly greater than that. So if you go to a different preamp, and you envision the possibility of eventually using a digital source as one of your main sources, the possibility of issues arising from the unusually high gain of the ET5 and perhaps other CJ preamps (in combination with your particular speakers and amplifier) is a factor that should be considered.

Good luck. Regards,

Pkelly, I'm wondering if with your present CJ ET3SE you are having to operate the volume control undesirably close to the bottom of its range, especially with digital sources if you are using any.

The reason I ask is that your ET3SE, and also the ET5 you mentioned as a possibility, are spec'd as having unusually high gain (25 db). And I see in another of your recent threads that you are using Sonus Faber Elipsa SE speakers, rated at 91 db/2.83V/1m and 4 ohms, and Cary CAD 500MB amplifiers rated at 1000 watts into 4 ohms, with 1.42 volt sensitivity for full output power. That all suggests to me that you may have too much gain in your system to be optimal, and the same would be true if you went to an ET5.

The 12 db gain of the PrimaLuna preamp, which is more typical of the gain of most line stages, seems much more reasonable in the context of your particular system. To be sure it's clear, however, in saying that I am not expressing any opinion about the PrimaLuna's sonics, having no experience with it.

FWIW. Regards,
