Maestro M-15 and M-25R come complete with two interchangeable face plates 

MAESTRO M-15 & M-25R INTEGRATED AMPLIFIERS

 

We've developed a new tube integrated with a 

High & Low Frequency Boost /Cut adjustment which allow you to adjust for the recording: Perfectly recorded high-resolution music would be set to the off or flat position, whereas Classic Rock might need a bass-boost and an overly bright recording might need an adjustment in the upper register. 

The high and low contour (boost-cut) might seem a little nostalgic but make no mistake it's a reference control as is the audiophile balance, mute, and fully summing mono switch.  The M-15 and M-25R integrateds will drive any Viking loudspeaker with dead quiet power.

The M-15 and M-25R Integrated Amplifiers are two of the quietest tube amplifiers you will ever hear...Period!
