Equipment that has made you 'stop' looking?

Verity Parsifals. I've listened to a LOT of speakers over the past decade and, for the money, these are the ticket. Don't know that I'll ever be that tempted to change them out, knowing that I would probably have to spend twice as much to realize any improved sound...

Moerch DP-6 tonearm on a modified Lenco L-75 turntable.

Definitely for now the TRL modded Marantz SA-14. Then TRL latest amp the "225" @ 5,000.00. You're really there!!

audio aero capitole,vtl tiny triodes,decapo i monitors and I'm finished.

Jadis JP80MC preamp stopped me from upgrading for over 10 years, and then the replacement was the next model up in the line, the JP200MC preamp, which I don't believe I'll ever give up till I start losing my hearing completely. Same can be said for my Forsell CD transport (until it breaks down and can't be repaired), which has been in my system for 10 years plus, and the Audio Logic DAC, which has been in my system that long as well (though it has been upgraded a few times). Also, the Day Sequerra FM Reference came into my system over 12 years ago and won't be leaving it (again, had some upgrades done rexcently, well worth it sonically) until there are no FM broadcasts to be received, and then I will probably keep it as a museum piece. Finally, the Basis Ovation turntable, a great design that I've owned about 15 years and don't have any plans to replace (again, it was upgraded to incorporate the Debut's bearing, platter and vacuum hold-down system).
