F5 Headamp ?

In the meantime, let me tease you with pictures of the first working prototypes of the F5X-HA.

Please include me for 1 set of v2 pcbs. I just tested Cloud85's and it has tube-like qualities. Warm smooth but with enough details and good refinement

I would not describe it like that.
It has much more bass control and current delivering capabilities than a typical tube amp.
Instead I would describe it as a typical Class A FET amp with high bias.

We already have the boards.
We want them (V2) to be tested first before distributing.
They just arrived at the Ve Beta testers. And they need time to build.

If you cannot wait we can try to send your earlier.
(Cannot promise when exactly, as everyone is busy and sending one off takes a lot of effort in proportion.)
But I guess you have a V1 Beta tester nearby to help.
So only limited risk.

A one time offer to V2 (and V1) subscribers :

We are doing a new batch of F5-HA case parts for ourselves, and Mark has offer to do another 10 or so for the subscribers.
They will be identical to my own case here :

(Only exception being that all the internal heat conducting angles will be black anodised.)

The case is based on a Chinese 2107 headamp case :
Z 2107 Full Aluminum Power Amplifier Enclosure Headphone Amp Preamp Case DIY | eBay

with the following additional parts :
machined front plate for mini XLR, LED, etc.
new top plate with side vents
new rear plate to suit PCB geometry
fully machined & drilled bottom plate (vented)
aluminium feet with O-Ring isolators
2 pairs heat conducting angles
1x thumb wheel for LDR CCS.

The only option we'll offer is a blank front plate (if you wish to use other sockets and volume).
Price would be about 750 HKD including Paypal fees excluding shipment.

Shipped weight about 3kg.
You can get an estimate for postage here :
Hongkong Post - Parcel

Please kindly indicate interest so that we can estimate batch size.
