Appayya Diksita in his commentary on Ananda-lahiri states:


veda vibhagarTham ivavatheernena sakala veda tatparyabhijnena sarvajna
siromanina veda vyasena pulastya varadana labdha devatah paramarthya
videna parasarena anyishcha maharshibih vedopa ..............


atho narayanah parabrahma kotireva iti asmakam siddhantah:


meaning:


Our tongue would not rise to assert in the wake of a few mantras,
arthavadas and puranic statements found in some insignificant place that
sri narayana is a jiva, since He has been worshipped by sadhus as Gohead
and has been confirmingly declared as Parabrahman in Mahabharata,
vishnu-purana and other religious works, which were composed solely for
bringing out the essence of vedas by eminent sages like Veda Vyasa, who
classified and analyzed the vedas and Parasara, who was blessed with the
true knowledge about Godhead by Sage Pulastya.  If any such attempt were
made, OUR HEADS WOULD BURST INTO A HUNDRED PIECES. 
<color><param>ffff,0000,0000</param>We would be guilty of treachery to
the vedas, sages and deity itself.  Therefore, it is our considered
opinion that Narayana alone qualifies for the title of GODHEAD



</color>I was always told that Appayya Diksita was a very great scholar,
who had bias to Saivism in his early days, but always relied on valid
testimony ie. pramanas like Vedas, Vishnu Purana etc. (note Sri
Sankaracharya only quotes from Vishnu purana and not others ).  This
quote clarifies his position.
