You could aslo look at the Pro-ject range, they make a passive preamp that has had a lot of praise for the price

This community is paid for by the proceeds of Graham Slee Projects Limited and as such has a policy of not allowing the promotion of other brands that could be classed as competitors. If a member wishes to let another member know such things the private messenger service provided for free by us to members should be used.

No other manufacturer's forum I am aware of would allow promotion of a competing brand.

Just designing one hopefully to launch in the Autumn partly in response to this topic.

I've been often asked for a box that does "single-sided" domestic in to balanced out.

Or in this case a volume control with same.

And often requested to simply do a two or three input preamp.

It would seem there is room in the market for an absolutely-no-frills "little box" preamp, and there are passive ones, but often some gain (amplification) is required for matching a low output to a high input power amp - plus, balanced cannot be done passively.

And seeing that used to be my daily "bread and butter" job some 16-20 years ago...

One or two loose ends to tie up and I'm on to it.

i always wondered if you could increase the gain using a transformer bassed passive preamp. 

I did think of going down the passive route but got a pre amp with the power amp i found. Looked at a ladder design volume control and thought you could do a balanced version with this?
