Mapletree Audio Design Ear+ Purist Headphone Amplifier

Further Information

Hi Everyone, 

I'm in the process of assisting a close friend liquidate a vast majority of his Hi Fi equipment as he transitioned into Aged Care late last year and unfortunately couldn't take the majority of his equipment with him to the centre.  

My friend Gary bought this MAD ( Mapletree Audio Design ) Ear+ purist tube headphone amplifier direct from Dr. Lloyd Peppard ( founder of Mapletree Audio Design ) as an assembled production unit with NOS tubes and teamed it up with his Sennheiser HD600 headphone as well as a pair of Grado SR80s headphones. When his HD600 failed, he upgraded to the Sennheiser HD800 headphones and continued to use this great little tube amplifier to power them also.  This headphone amplifier was commissioned/bought around circa 2007 from Mapletree Audio Design and has worked flawlessly through all the years of ownership and playback and the only other cost for Gary was that due to his love and regular use of this amplifier that eventually he replaced all the tubes on it only about 18 months ago and also has another set of spare NOS tubes that will be included in this sale. 

The only minus points I can assign to this little sonic marvel is age related cosmetic wear where there are a few small tiny pits on the case work,  the original stick on labels for the rear RCA sockets and serial number had previously detached and were replaced non original labels and some slight fading on the MAD logo on top of the power transformer casing. My friend Gary had really "babied" this headphone amplifier as it was his 

retirement present to himself after he retired from work. 

I have tested this beaut headphone amplifier over the last month for several hours each week and it's performed nicely with no issues and it's silent as. If I didn't already own one of these myself, I would be buying this off my friend, but because I already have one myself it's pointless to have 2 of the same thing. This Ear+ purist is no longer available from Mapletree Audio Design since Dr Lloyd Peppard seems to have completely handed over the business to Al Freundorfer due to his failing eyesight.
