    sorry have to excuse my ignorance here but what is a passive preamp?

    It is basically a potentiometer in a box - a volume control and nothing else. It is usually in the form of a stepped attenuator (a multi-position switch where you subtract resistance at each discrete step clockwise)

    LLOL - on SO many threads, if he is reading any of what is being posted I can only hope that the sense of humour surpasses the frustration!

    I had an Audio Synthesis passive one time. Highly regarded and rightly so. But it didn’t suite me. It’s clinical with an absence of punch. If you like something small scale like string quartets it’s unbeatable. Basically it’s a bit niche. I’ve a Grad1 yet I got close to buying the Allergi in the classified on here. It’s that good but limited in the stuff it’s good at.

    I’ve had Khozmo, and Audio Synthesis Dax Decade straight into power amps always felt something missing. I must like distorted tunes.

    Yes, I think they are worth trying but clearly won’t suit everyone.

    I had a Grad 1 about 15 years ago. All round better than the 32.5 that it replaced.
    I gutted the 32.5 shoebox and stuffed it with PFM’s very own Starfish project board.

    This turned out to be better than the Grad, better than the Naim 52 I had, even.
    The Starfish is still my preamp to date.

    The TPX2 was an updated TPX1 I believe. The APX2 was the big daddy.

    Over time I have had APX2, APX4, TPX1 and TPX2. The APX power supplies go back a long way and were essentially hicap replacements, and very effective at that. The TPX1 is a slimmer version of the APX2 and was "original equipment" with the Grad1. The TPX2 came after the TPX1 and is much more than an updated TPX1 being at least twice the size the the TPX1 and a massive improvement with the Grad1. The only downsides of the TPX2 are that it makes a somewhat inelegant pairing with the Grad 1 and doesn't fit on a Naim sized rack. The Grad1 and TPX2 combination does sound exceptionally good though!

    yes it seems there were more Grad1 then TPX2 well available now anyways

    I think you're right. The TPX1 and 2 were sold alongside each other so the TPX2 effectively replaced the APX2 at some point. I still have my APX2

    I had a Grad 1 with its dedicated PSU (not sure what it was called), an A260Z power amp and one of Les's phono stages with another PSU.

    Absolutely amazing service from Les, but I ultimately preferred an AVI Lab Series Integrated with built in phono stage.
