“Hi Fi World” August 2007 said:
“Class A without tears, this new incarnation adds power and control to the A21a’s traditional transparency and musical ease ... Gorgeous.”

“Ultra Hi Fidelity” December 2007 said:
"I was expecting a good, honest performance, something that would make me feel good, as Sugden used to.
But not this ... not something that would even cast doubts about some aspects of our reference system".

“Hi Fi Choice” said:
"The Sugden combo draws its strength from a classic amp design.
One which, for sheer musicality, showed a clean pair of heels to every other amp in the group.
The CD player’s no slouch, either.
Together they work beautifully and look rather smart.
A revelation and clear Best Buy".
