Canary Audio M500

I am the New Zealand Canary importer and I am selling my demo pair of the fantastic Canary Audio M500 Monoblocks. 
*IMPORTANT INFORMATION* ......These are 230V Models.

All Canary Audio products are hand made in California.

The M500s are a pair of push pull Monoblocks using 4 x 300B tubes per side to give a healthy 50watts RMS. You get the smooth musical presentation of the 300B tube with some very useable power courtesy of the 4 x 300B tubes per side in push pull mode.    
These are beloved by Definitive Audio in UK who called these M500 monoblocks "Superb". This is the company that sells Kondo in UK so they have extremely fine products to compare Canary to.   
They are fitted with 4 x Shuguang black Treasure 300Z tubes and 2 x black Treasure CV-181Z tubes per monoblock 
The sale price INCLUDES these 300B Tubes and CV181Z Tubes.   
There are in excellent condition with no marks or scratches. 
The M500 monoblocks sit above the CA339 monoblocks in Canary's range with better components and a simpler more sophisticated biasing system

Whilst being on demo they have performed flawlessly.

These amplifiers new are US$15,000. The 8 x 300B tubes new are over US$2000.
I am asking US$6900 and this includes free delivery by TNT Couriers anywhere in the world.
