Back when this version was being sold, the entry level recommendation was Rotel and for a bit more B&K and especially PSE.
I know it might be a bit of a budget stretch, but instead of a budget intergrated; I would recommend a used early generation McCormack power amp and an inexpensive passive pre for a rather large increase in sound quality. No phono/ no remote, but the high output CAL is great match for a passive, and McCormack's / Vandy's are terrific match regardless of budget.
