Question Driving Pass Amps direct without pre-amp? With a Wadia, experience anyone?

I was wondering if some of you have driven any Pass Amps from the past (Thresholds, Alephs) or new X series, directly from their CD Player.

I am thinking of getting a used Wadia 6 or 16, or maybe an 850. I'd of course be happy to spare the cost of the pre-amp, especially if it helps with transparency and some bla-blah I read about this way to hook-up.

And by sparing the pre-amp, I'd financially be able to get a newer/better Pass model... ;-)

On the contrary, some folks told me this just does not work properly... ?

I read that some input impedances of some Pass Amps where "special", how would that translate in this situation? Will the Wadia drive the amp to an adequate volume?

Thanks in advance for any feedback...

I have used both a 6 and a 16 directly, and they work
like they're made for each other - no problem at all.

I'm sure the 850 is equally fine.

Default Wadia into Pass X

I run my Wadia 830 staright into my X -250 and it is the best. Ad any thing else in t he chain detracts from the sound quality, from very litlle to alot depending on what you have added.

I just started using an Adcom GFP 750 preamp so I can run a phono stage in my system. In Passive mode it effects the signal very , very litlle. But still if you A/B the two sets ups it is slightly more transparent and detailed with the Wadia direct into the Amp. It has two be, you have eliminated a set of interconnects and and one componet ( whether it is passive or not ).
