Thank you

We would like to thank you for choosing our 

Mystère

 pa21 stereo power am-

plifier as an important part of your music system. 

Working with components across the spectrum day in and day out for more 

than 30 years led us to adopt an unassailable philosophy: the only acceptable 

level of quality for the products we produce is the highest quality, regardless 

of  price point.

 

We have staked our reputation on this and are certain that the products we’ve 

already brought to market reflect this principle. We feel comfortable in stating 

that our standing in the audio community is of the highest order and we’re 

certain that 

Mystère

 will only serve to enhance that standing.

We hope that the 

Mystère

 pa21 stereo power amplifier 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.mystere-eu.com website you will find links to these and other websites.

Our prices are kept low by using word-of-mouth and customer feedback, and 

we would appreciate hearing what you have to say about our product. If you 

need service during or after the warranty period, please contact us.

Thanks again for your support!
