Many great choices out there including Sansui as mentioned.
I feel of all my SS restored vintage integrated amps (20 or so) the Kenwood 7100 is the peach without breaking the bank.
As long as a pre/pwr loop is not needed, it seems to make the best sounds with a variety of speakers and overall more reliable than the KA-8100 which suffer from noisy Filter switches (buttons).
The Marantz 1060 is also worth mentioning as its MM phono section is a very good, but overall it is a bit darker overall by comparison.
Not sure just how similar these are to the KA-3500 & 1070 although I suspect similar characteristics with the Kenwood being Direct Coupled & the Marantz capacitor coupled.
