MAESTRO

Vacuum Tube Amplification

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!

Hi David,

I've listened to my Maestro P35-R (Gottenburg) Reference Tube Preamp for some hours now and I'm very happy with this great Tube Preamp for clarity, focus, extension, soundstage, imaging, palpability and extraordinary silence. The sound is very natural and detailed really and it's very important for me. I've already used your High-Low Contour Adjustment to improve a recording sound and I have to say I'm very amazed. The volume control and the rest of controls work great too...this is the best Tube Preamp I've ever listened to by far. Congratulations David for such an exceptional Preamp. Here you are attached several pics.

 

Best regards,

The M-15 tube integrated is my third tube integrated amplifier after a long history with top solid state gear.  The Maestro is the least expensive amplifier of the tube amps in my ..what's becoming my amplifier collection. The Maestro M-15 at first look is not as fancy or as heavy as the other two amps which I will not name because the Maestro amplifier is far better then either the Korean or Japanese units: more musical, more powerful, and absolutely quieter than either by a good margin the M-15 is dead quiet just as they said. M-25R is on my hit list for my next amplifier acquisition.
