Amplfiers that Sound like Pass 30.8 that are not so heavy

The CODA #8 is an excellent amp. Only reason I would sell it is to get the CODA #16 which is a bit better. The CODA drives my Thiel CS3.7 great. It can go down to 2 Ohms, though I forgot the numbers.

I actually move my CODA #8 around rather frequently, so I am glad it is not heavy. I alternate with some other amps between my RAAL SR1a headphones and the Thiel CS3.7. The other amp next week will be a KRELL Duo 175XD which may also satisfy the OP's needs.

The KRELL is a bit smoother sounding on the SR1a (I have a KRELL K-300i in another room) while I like the CODA #8 a bit more on the Thiel CS3.7.  The KRELL is a very relaxing sounding amp. The KRELL 175XD is 60 lbs.

+1 on agd if you want pass labs level of sound, and much less weight

Unless the amp power supply is a switching type(very rare) a large power supply is desirable but heavy due to a large trnasformer. Great power supplies don't show up in standard amp specs but are the most significant factor in the amp's performance.

Also if you like the sound of the Pass that's hard to get. A big factor in this amp besides rich class A before going to A/B is there is no overall feedback loop like over 99% of amps. No loop feedback makes a big affect on an amp's sound.

Ayre is nothing like Pass, even tho a genius also designed it.

A used Nagra classic amp. Musical detailed and a hint of warmth
