Description

Britaudio is an authorized Rothwell dealer. This is an upgraded version of the great sounding Rialto phono stage. All the capacitors have been replaced with high quality Nichicon 'Fine Gold' types and a much larger 600mA power supply. The end result is more of everything, bigger soundstage, larger lower end, smoother top and mid range as well as a more three dimensional soundstage. These upgrades are carried out in house at Britaudio. Hi-Fi Choice group test winner February 2014. Hi-Fi News, "Outstanding product". Hand made in England. Don't be fooled by the Rialto's relative affordability; this is a genuine high-end phono stage and competes way above its price range. The first phono stage to bear the Rothwell name was designed as far back as 1989 and was debuted at the London Hi-Fi Show of 1990 (it was an expensive valve/tube design with many of the features subsequently adopted by other manufacturers, like a large outboard power supply and selectable cartridge loading). The goal when designing the Rialto was to achieve high-end performance without the high-end price tag. To this end, every effort was put into maximizing sound quality and everything that has no bearing on sound quality was sacrificed. The Rialto uses discrete components throughout with no op-amps, so the circuit operates in Class A with no crossover distortion. The components are audiophile-grade and the circuit has been designed to achieve low noise even with low output moving coils. However, for optimum performance from an MC cartridge, we recommend using the Rothwell MCL/MCX/MC1 step up transformer into the MM stage of the Rialto. External factory supplied power supply is included.
