Magnification was not a commercial success upon its release, peaking at No. 71 on the UK Albums Chart and No. 186 on the Billboard 200. Yes toured the album with the six-month Yessymphonic Tour, playing each show with an orchestra. Magnification was reissued several times with bonus tracks. Yes returned to a five-member formation with the return of keyboardist Rick Wakeman in April 2002.
"Can You Imagine" is sung by Squire on lead vocals with Anderson on backing vocals. It was originally recorded as a demo in 1981 entitled "Can You See" for the proposed supergroupXYZ with Squire, White and Jimmy Page.
Magnification received a warm reception from critics and fans, although not on the level of older albums such as Fragile or Close to the Edge. It reached No. 71 in the UK and No. 186 in the US during a chart stay of 1 week.
The album was reissued in 2002 as a 2-disc limited edition set with alternate artwork; the second disc contains three live tracks and a CD-ROM with an interview with Anderson, a music video of "Don't Go", and a live video performance of "The Gates of Delirium". Magnification was also included as part of the compilation studio album box set Essentially Yes in 2006.
