When is it time to up grade?

When those evil upgrade gods whisper in my ears, or every week which ever comes first.

My speakers are Castle Howards. They work well in my crowded living room.I haven't auditioned any new speakers in a long time. Are the Castles the weak link? Replacements?

How about some speakers?

Whenever the "preamp deal of the century" becomes "the preamp deal of the millennium". Then, at least, I'll know.

When you are no longer emotionally "moved" by your present gear...

You mean you haven't yet?

When your checking account is no longer overdrawn ;~)

One thing I would look for is a used Aesthetix Rhea phono stage. This is a very good phono. If you prefer to look for SS in that range, check out the Pass Labs Xono. I can't imagine you'd be disappointed with either.

Don't do anything foolish like dumping solid state for tubes without seriously auditioning the particular piece of gear. If tubes are the answer, your question is too vague.

when you have the money and the time. Move from ss to tubes. cartridge and speakers are probably the most colored components in your system.

What time is it?
