Up for sale a Woo Audio WA5-LE top of the line headphone amplifier in great condition. Works perfectly, I'm the original owner.

This WA5-LE (Gen 1) features a number of significant upgrades above the standard model, each one of which has elevated its sound noticeably over a stock Woo amp. It‘s well north of £2K on top of purchase price I‘ve put into these moves (& each has felt worth the spend).

- Internal parts upgrade package from Woo at purchase (V-Caps, Jensen caps, etc)
- Had Revelation Audio in the US create me a bespoke Cryo Silver umbilical chord to connect the Power and Amp sections
- Recently purchased top end tubes as a final upgrade, these are all matched pairs and practically new with a few tens/low hundreds of hours on them including PSVANE ACME 300Bs, PSVANE ACME 274Bs and pristine, rare NOS Ken Rad black glass 6SN7s

This has a wonderful 300B sound and a choice of high and low impedance pots to carefully match with headphones. Works amazingly to partner digital front ends, whilst maintaining an inredibly big soundstage and gorgeous detail. I use it with Senn HD800, HD800S, Meze Empyrean and Final Audio D8000 Pro and all of them shine through it. You should barely trouble 10 O'clock on the volume almost all headphones - it has masses of power.

I have listened to a number of 300B tubes. I had the Sophia Royal Princess before - which these better in every conceivable way - these PSVANE ACME 300Bs sit right at the summit alongside Elrog / Takatsuki (both of which I’ve heard in this amp). Like the 274Bs, the ACMEs are a flawless matched pair and sound thoroughly excellent.

Happy to demo to any potential buyer in Cumbria. This is a very heavy package, so pickup preferred, careful delivery would be possible, but most likely within the UK.

Option 1 - £2550 includes all above tubes, full package - Bear in mind a matched pair of these wonderful 300Bs are around £1000, 274Bs are £440, a top NOS matched pair of these Ken Rad black glass 6SN7s (if you can find these) around £250

or

Option 2 - £2000 with a decent matched pair of very highly regarded Amperex Philips Holland 5R4GYS [5R4GY] rectifier tubes and my older pair of Ken Rad black glass 6SN7s. Both are used, but still sound outstanding and would not be near end of life in terms of hours on them. These are great tubes and frankly far, far superior to your average Chinese, Russian NOS tube options at only £200 for the four tubes above the below option. No 300B tubes

Option 3 - £1800 - WA5-LE Amp, Woo upgraded internals, RAL cryogenic silver cable, No tubes
