• No more 12AX7 tubes in the DiaLogue Premium range of products. Instead of a 12AX7/12AU7
combination in each channel, we use a double 12AU7 combination. Lower distortion levels, higher
level of sound quality. Distortion levels in the first stage have dropped with a factor of 5 at low
levels to at least 20 at higher levels, above 1V.
• All new PrimaLuna PTP™ (Power Transformer Protection) circuit. When the power transformer
overheats due to environmental circumstances, overloading or some problem in the unit, an
internal thermal switch breaks the primary, allowing the unit to cool down before harm is done.
After it’s cooled, contact is restored and if nothing is broken, the amp will repower and function
properly.
• All new PrimaLuna OTP™ (Output Transformer Protection) circuit which further protects the
amplifier.
• LIVE side of AC input connector indicated by aluminium color screw.
PrimaLuna SilverLabel tubes are pre-selected by us following our simple 60 out of 100 rule (PTS™ -
Premium Tube Selection) and as such, are already “special” when compared to other standard tubes
on the market. Additionally, for certain models we have our GoldLabel tubes, which are available from
us and several other parties if you wish to upgrade. In the USA, Upscale Audio's inventory of New Old
Stock tubes (which is another thing you might want to experiment with) is the largest you can find.
Elsewhere, independent suppliers can assist you to make your best choice.
We hope that the PrimaLuna DiaLogue Premium Poweramplifier will make you want to follow our next
steps in expanding this new range of products. If you have any questions or comments, don't hesitate
to contact us. You can also share your thoughts with others at www.audioreview.com or other review
sites. On the www.primaluna.nl website you will find links to these and other websites. We keep our
prices low by relying on word-of-mouth and customer feedback, and we would appreciate hearing what
you have to say about our product. Finally, if you need service during or after the warranty period,
please don’t hesitate to contact us.
Thanks again for your support!
