If you already have speakers you could replace the full size amp with a mini amp.

• SMSL SA50 $61.
• SMSL SA100 with Bluetooth.
• SMSL SA300 with Infineon's new class D amp chip.
• SMSL A2 has 2 inputs and sub out.
• Micca OriGain, Micca OriGain + DAC
• SMSL AD18, Topping MX3 also have USB input DAC and sub out.
• LOXJIE A10
• FX-Audio FX202A $39.

A stylus upgrade for the LP60 from conical to elliptical is LP GEAR CFN3600LE $29 or with a new belt $39.

That receiver doesn’t have a DAC it seems. If you don’t need AM/FM and want connectivity options, something like the Topping MX3 would work well, especially on a desk.

Otherwise, I’d go with a cheap Denon or Yamaha over the Sony.
