Pass X-150 X Levinson 334

Hi Famaraca. Pls give more info: Which speakers do you have and what kind of music do you listen to... partnering equip.

Having listened to both with their respective partnering pre, but in DIFFERENT home systems, I lean towards the system with the Pass. Pls note: different systems. I agree with Lev regarding the mid, but could add that the Pass system sounded slightly closer to "natural" sound overall. The music was classical.
Good luck!

Thanks to Lev and Greg
My current front end is:Oracle Delphi+ET-2+Koetsu Rosewood Sig.,Accuphase DP-65V cd player.Krell KSP-7b Pre-Amp and Apogee Caliper Sig.speakers.
I listen mainly to Modern Jazz(DMP,GRP labels)
Do you knows the quality construction?I saw the 334 inside(superb),but not the X-150.
Thank you

The Levinson gear is built better than pretty much anything I have ever seen. There is an audio store in White Plains New York That had a 332 In peices just to show how complex these amps actually are. It blew my mind. The Pass is really good gear. Even so I will never switch from my 335. And the 334 has the same sound just lees power than the 335. You cant go wrong. Even if you didnt like the Levinson (you will) you can get your money back on the used market. Good luck

Famaraca, can you check out the synergy either of these amps w/ your Krell -- I do mean, try it out. This may be a decisive factor (I can't tell offhand -- maybe Lev has knows?). Either amp should drive the speakers superbly...
Pass design & construction are purportedly top-notch; I have never taken one apart. As to Levinsons, see Lev above.
Accuphase, eh, you lucky devil... (I love the sound of those machines).
Good luck!

I sold my #331 in favor of the Pass Labs Aleph 4. I had both in the house for a couple months, going back and forth to make sure I wasn't crazy. The Pass was much more natural and airy. The Lev sounded dull in comparison. I invited some other audiophile friends over to listen and they agreed. I have a comment about Lev335's response. Nelson Pass is proud of his amp design because its NOT complex. In fact the signal path of the Aleph series is only 2 stages and very few components. I think he was on to something there. Pass amps are a solid state equivilent of the Single Ended Triode.
