Refurbish a classic amp or replace it?


I have a Mark Levinson ML3 amplifier that is over 20 years old. It sounds great in my system and I am considering whether to have it refurbished/upgraded. I spoke to one place that only does service and upgrades and was told not to do it and that I should sell the ML3 and use the money (plus a lot more)to buy a new amp instead. If I buy a new amp, it would probably be a Pass Labs. I would like to hear from other members who have had similar experiences. Also, I would appreciate recommendations for where to have the ML3 refurbished/upgraded if I decide to go that route. Thanks

I take a know what your are getting approach. Hold on to and not upgrade the ML3. Seek a replacement that you can bring into your system and hear via a dealer that will give you a loaner. Once you have 'better' sound, buy it and sell off the ML3. Most people I know that have done upgrades of their own equipment have been disappointed and felt the value was not good.
Joseph Chow is a good source for upgrades. I believe he also has a Mark Levinson amp in his system. Also, remember that most electronics that are 20 years old or more probably need to have their electrolytic caps replaced due to the old caps life expectancy running out. Electrolytics have also improved a bit over the last 20 years, so if done right, your amp should come out better than when new. If you like the Levinson sound now, a little refurbishing and upgrading will be a very cost-effective approach versus buying another amp.
I think it depends on the amp and the manufacturer. Some amps have "classic" status and some brands have better customer service and reputation. Since their take over of Harmon has not garnered much praise here for their handling of ML gear. Having classic gear modded by other than the manufacturer is risky, especially for resale value. There are exceptions like Jon Soderberg with Threshold gear.

I am having my Accuphase P-300's refurbed, they are fantastic even by todays standards and then some.

If your amp is only twenty years old,just use it the way it is,and enjoy...

I once had a very popular amp modded and was VERY unhappy with the outcome.

It's risky,unless you heard one and liked it.

My 2 cents....
