Speakers to hang on to for LIFE

I just acquired a Golden Tube Audio MK-II integrated amp. I too have had my Celestion speakers forever. Since this is my first tube amp, does anyone have any experience with Celestion speakers and tube amps of 50 watts? I was thinking of selling my Celestions for a newer set of more effiecent speakers.

Any thoughts or suggestions on how difficult a load the celestions put on a tube amp.

Also any recomendations for a new set of monitor speakers under $1000?

I own ADS 1290 since 1988,sound execellent,and still going strong.

I love my Martin Logan SL3's. Who says they cant ROCK. Hook em up to a couple of Rouge Audio 150 mono blocks and a Rel subwolfer.....Great. Had them 10 years. Going to replace the panels when I buy a house.

These Jadis Eurythmies have been in my system for a three years now and I have no desire to change. Are they the most accurate transducers out there? Almost certainly not. Do they make beautiful music? You betcha.

Have any of you experienced the Gryphon Poseidon speakers?
