Adding the Ultra 5 devices under the Lansche No.7, after I had installed the ESS racks and Ultra SS under the power amplifiers, was revelatory. All the qualities I’ve described about the ESS racks were taken to another level. The increase in resolution was mind-boggling. I’m not talking about hi-fi resolution or the presentation becoming more forward or etched, but rather that about hearing more musical information.
