renouncing the material life and the world of the flesh to focus on the spiritual, I just wish they’d get on with it and leave me out of the loop. If a McIntosh amp the calibre and completeness of the MA8900 stand between redemption and me, I’ll take the Mc. As for spirituality, Van The Man belting out “Ballerina’’ aided by the grace, power, presence and dynamic clout of the MA8900 is as much “otherworldliness” as I need these days. Should I need more, I’ll press repeat on my Audio Research CD player or re-cue the SME V tonearm on my turntable. Piles of lucre aside, what you’ll also need to unbox and install an amp of this size and weight are forceps like a gorilla. Or in my case a dutiful son and a couple of audio buddies built like Tarzan. The Mc’s delivery driver was hairy but had neither the physique of ape or ape-man. As he told me that he had a “very heavy box on a pallet… to deliver”, I could sense his angst. No wonder, the MA8900 weighed 63.5 Kgs including pallet. Without the pallet, it was still a back torturing 43.5 Kgs.

outputs. Yes, there’s also a headphone output, while the headphone amp is loaded with Mc’s patented technologies. The USB input processes signals up to 32-bit/384kHz and supports DSD256, DXD256 and DXD 384kHz. McIntosh describes the MA8900 as a “next generation’’ model. Meaning, when it comes to the ever-changing world of digital audio, it sports features that make it relatively future proof. Each digital input, for example, cohabits in a McIntosh developed DA1 Digital Audio Module that supports an 8-channel, 32-bit DAC used in Quad Balanced mode with six digital inputs. Owners can give each input a custom name and more importantly, the 8900 is Mc’s first integrated where its input works indecently. But here’s the thing. McIntosh is now using digital modules that are easy to replace. Design features that ensure the 8900 and like designed Mc models remain future proof. Elsewhere this amp is loaded with patented technologies including autoformer output stages and fuse-less protection circuits called ‘power guard’ and ‘sentry monitor’.
