Ah I see thanks, looks impressive !

The circuit is a class A, zero negative feedback, transimpedance MC amp. It actually runs at about 82db of gain but the RIAA topology is such that this is 'burnt off' in the RIAA correction. The indicated external PSU is a rather large dual mono, bipolar set-up with current chokes and common mode filters in the pre-reg. The psu proper on the gain boards is a bipolar, class A shunt reg based on one of Salas's designs.

Andy, try some resistors around around 250 ohm (220-280). It'll tame the treble peak you are hearing as a lack of bass definition.

Out of interest, can I take it that the equalisation is achieved passively? If so how many dB does the filter 'burn'?

Really looking forward to hearing one of these at some point. Is there likely to be one at Scalford?

One may be at Scalford as there are a few out there now (unlikely to be mine though).

You need to build a second 'portable' turntable Mark!

To be honest Guy, whilst that is an issue it isn't the key one. The truth is that the prospect of showing at Scalford just doesn't excite me - I would rather go round it. There would also be the whole politics of the Wam to navigate, you know the whole 'we're all amateur enthusiasts here....erm, except for the ones that aren't'.

Agreed. It's far more fun to be at, have a few beers & look around than to be stuck in a room for the day.

Precisely

. If you did want to hear mine you are always welcome Guy - hardly round the corner though.

Second day of reviewing the Paradise and I'm finding myself respecting this device more and more. I've just been comparing the intimacy of male and female vocals. Tonight I'm looking at it's ability of reproducing treble so I have a night of Van Halen, Deep Purple, Steve Vai and a few others.

Thanks, will do. I don't think I'm hearing any treble peak. I would actually say that guitars are sounding a little "blunted" not as raw as they should be. I've now heard this occur on several tracks from something as benign as the solo in Forgotton Sons (Marillion - Script for a Jesters Tear), to Eruption (Van Halen - Van Halen). The Paradise seems
to have a softer presentation when rendering class rock guitar solo's when compared to my Sugden+SUT combo.
