I will soon be replacing my Ultraverve with a preamp built my me. I am using the Erno Borbely line stage and power supply in a custom chassis with P&G volume control.
My present Ultravere is fitted with the the Gold point step attenuator with remote control, the output caps replaced with Mundorf SIO and some resistor upgrades. Extensive tube rolling has been done for the 6sn7 type.
I have been comparing both the preamps side by side for the past two months and all I can say that the Borbely line stage is better in most areas. It is amazing that this SS preamp sounds so harmonically rich, smooth and non fatiguing with excellent control of bass, glorious midrange and sweet extended highs.
The Ultraverve is also fantastic, one of the great preamp out there, but this one is a step up.
