PSB alpha B1's RULE.

I bought my daughter a set to go along with a NAD integrated. She had a party one time and someone turned up volume too much, and blew the tweeters.

So she brings them home to me for a fix. Ordered tweets and repaired. Sorta expensive.

But while I had them I connected them to a VTA ST-120, c-j MF-2250, and a NAD 3020B.
They could throw a piano image out of this world (jazz; Brubeck).

The B1's had one the best bang for the buck returns I've ever encountered. Driven by decent amplification, they add up to a lot more than the sum of their parts.

Having said that, the P5's are a definite step up from the B1's. Not the same $300 steal the B1's were, but most definitely a better, more refined speaker. I've had the P5's since shortly after they were released and they still surprise. After far too much procrastination, I recently got around to mass loading their stands and putting some of Herbie's small fat dots between them and the stands. Helped focus the soundstage and imaging improved. Very happy with the P5's doing audio duty on the video system.

Keeping tube filaments on obviously wears out the tubes faster.

  They're not running full bore in standby. Glowing and warm is all. Every system I've ever owned had/has this feature and I've never lost a tube due to filament failure.
  
  Going from stone cold to full power in an instant is what kills filaments, not low power standby mode.

    Wrong. Filament life is hours in use either at full current or minimal current. Turning on and does not burn out filaments.

      We will have to agree to disagree on this one.
      - I agree with Sondek - full voltage at turn on will further reduce lifetime and - Story 07:28:07 07/21/23 (0)

        just look at incandescent lightbulbs...How many times have you seen them burn out at turn on as opposed to lighting the room for 20 minutes?
        
        Right now for one of my room lights I have an incandescent that I'm using a variac on and the bulb is going on 3 years now. I always start it with 60vac and bring it up when needed. I have to do SOMETHING with the few that I still have
        
        So then, slow turn on with an indirectly heated rectifier like a GZ34 will and does increase lifetime
