    Default Bumpy's system

    I have just nearly completed my ideal system with the installation of a pair of DRD 45 monoblocks from Ron Welborne. When I bought these, they were good but not great and had hum through the speakers that with time became increasingly invasive on the music.

    With any bit of DIY kit one is at the mercy of the builder in terms of quality and component decisions. So I handed the amps over to Slawa at SW1X to have checked over, the hum reduced, and any in particular make a start at introducing components that have better SQ.

    As expected Slawa breathed his magic into the amps. Out went the solid state power supply with horrible sounding ceramic capacitors and in came a valve based rectified power supply. Inadequate capacitance on the B+ was boosted with Audionote Kaisei capacitors. The well reviewed EML solid plate 45's were retained but a better driver valve was used to balance its modern sound. Its now a great performer. Other components were improved on.

    I will follow up with pictures of my other components soon.
