I’m thinking of using the cheapest repairer, is this a good idea?

I honestly can’t say the cheapest anything is ever a really good idea!

You’re here because you are interested in quality equipment and work done well. Doing things cheaply is rarely compatible with doing them well. My Dad used to say:

“You get what you pay for, Mike.”

He was right. Surely, a better question would be:

“Do you want the work done cheaply, or do you want it done well?”

I see lots of equipment that’s been repaired cheaply and if you care about your hi-fi gear, it’s just not worth it. Cheap repairs often end up the most expensive option, because of collateral damage, poor parts and work that has to be rectified.

The overall quality of work and service is what should matter most. If the lowest price is your only concern, you really only have some very shonky repairer options and results that correlate well with that.
