Linn Urika - Schematic and Circuit Description wanted

[tiefbassuebertr]

The circuit for the signal processing of the modell "LINTO" and the RIAA stages from Linn's preamp model "LK-1" and "KAIRN" are nearly identical - go to

According the picture under

Linn's Urika works with integrated operational amplifiers (two linear gain stages and passive RIAA network).
Are here special approaches realized ? What kind of operational amplifiers are in use ?
Maybe one of the members can upload schematic und additional informations like test reviews and listening test reports.

Thank you very much.

any news ?

This Urika looks really horrible inside. The music is mangled through a huge number of opapms, this sounds flat and lifeless with much recessed midrange for sure. Good match to Linn cartridges, in other words.
The old Linto at least had a decency of being semi-discrete with one TL074 in a feedback loop. Not the last word on openness or presence but decent sound after all.
Modern people only want to listen to bass, bass and more bass. They don't even know how a proper midrange sounds.
Sorry if this message not adding any useful info.

I strongly doubt if this statement can be made in general if as approach an integrated solution was favored. There are in the meantime an extremly wide range of operational amplifiers available (TI, Burr Brown, Analog devices or Linear Technology are only a few amount of examples).
Schematic from Linn Linto and LK-1 are here:
