My Classe CP700 preamp needs service

I would only send any of my gear to where it was born.......they have the parts, resources, and techs to repair it properly

Classe is a great company that manufactures great products to be their best at a specific price point. If you are having problems ( and obviously, you are), then I would send it back to Classe (Canada) for repair. I am sure that you will find they are passionate about their equipment, and can give you ideas on upgrades if any are recommended. You can read plenty of horror stories about poor service from many companies that advertise for "upgrades" or "mods." My perception is that many mods do not produce the effect they promise. If they did, you would see less of the modded units for sale used here on Audiogon. Also, once some "passionate" tech upgrades your unit it may make it difficult to have anyone else repair it if anything goes wrong in the future. This is just my two cents. 

I sent my Magnum Dynalab MD90 for service a while back.  Fortunately they have a NY address where they receive items so shipping was cheap.  They were great to deal with, in fact they allowed me to trade that unit in for a Certified Used MD102, the tuner I always wanted but couldn't afford.   The repair would have only been $150 which was more than reasonable.....  I thought my tuner plus $700 was more than fair, when I received it I thought it looked like a brand new unit.  

Classe' makes great stuff I would imagine they will repair it for a fair price.   

Thank you for your posts. My CP700 is going back to Classe today! Joe
