How often do you change components?

My reference is live unamplified music so no matter how often I make changes my reference stays the same.

I try to keep a component at least four to six months. Many components can take up to 600 hours to break in and settle. (ie: Audio Research SD 135 Stereo Amplifier)

After break-in I usually will take another three or four weeks to put it through its paces with various types of music and power cord trials.

A few times I have been undecided and had components waiting in the que to be added to the system. If it is a deal and the price is right I may take a flier on a piece that I anticipate working well for me. I can worry about selling the loser later.

I once had four SACD players and three pair of speakers at the same time. Rare for me! Everything I was looking for came on the used market at the same time!

With every tire rotation.

When I averaged it out over the long term it worked out to about one major component per year.

Nice one Audiofeil.

While in SQ flux, about once every 2 years.

Do your audio friends listen to and scrutinized the differences in you car audio system after the rotations?

Once a week!!

look under Tbromgard's system for my 2 cents worth on this subject. SORRY for the dumb mistake...!
