Best Headphones & Amp---Opinions Please


I have a B&W / Lexicon centered high-end system. Just discovered the joy of listening to headphones. Have the Senn 650's with an upgraded 15 foot Cardas cable (no headphone amp) connected directly to my Onkyo 905 receiver. I would like to "push the envelope" in this area by upgrading to whatever my fellow aduiogoner's may suggest.

I would like opinion on the best equipment available. Cost is not a major consideration, but, I would rather not spend considerably more just for a 5 to 10% improvement--in other words---the most bang for the bucks.

Thanks in advance for your assistance--Dave

I've ordered two Red Wine Audio Isabellina HPA head amp.
It is pricey but has features worth considering.
Here is why:
- runs on batteries which power charges are monitored and optimized by custom SMART module.
- NOS DAC with USB-in for computer files.
- remote controlled
- can be used as a digital preamp ( variable volume option )
- V-caps (new . Which in my opinion give RWA somewhat more open presentation and better resolution.

Your cans are also recommended by Vinnie (RWA) as a perfect match for his head-amp.

I will be using one for can setup (2nd system) and the other one as a dedicated digital preamplifier.

Just my two cents

Also the top of the line Darkvoice amps on ebay.
Lots of other really nice headphone amps out there. I suggest you check out www.head-case.org and www.head-fi.org for more info before making a choice. i think going balanced is the way to go with the Senns.
The headphone jacks on the Manley 300B preamp and the Cary 300sei integrated amp are also very good.
