The units I have are 240V units or they say at the rear panels of the amps. The repaired unit is past the 100+ hours mark. Total time on the repaired unit is around 360+ hours & so far no issue. The failure came from C5, one of the caps. This caused a loss of bias resulting in orange glowing light bulb like tubes on one bank. Of course a whole bunch of resistors were also affected etc. While this first breakdown occurred, the monos were attached to my big Torus which has voltage regulation.

I have since changed to Shunyata passive conditioners when the second unit failed. Symptoms of failure was slightly different but the cause was the same - loss of bias. So, parts were sent & amp was hauled away for repairs. Expect to receive it back today.

Fingers crossed.

In the meantime, at 360+ hrs the first pair i starting to sing nicely . 100+ to 300+ hrs were dark days of doubt & anguish

Regards,
Joe Ling

Amplification - Naim Statement

Speakers - ProAc Carbon 8 + JL FM113 x2 (replacement purchased - Stella Utopia EVO but due to lockdown, could be a year's wait)

Purepower 2000 x 2 (&$@#% but
sounds nice)

Good to hear.

I bought a second pair so that I have 100% redundancy. The second unit has been repaired & delivered to me last night.
