The Marantz 4270 also uses the WC-22 wood case. The wood case makes quite a difference in the final sale price of these units these days. A fully restored, fine condition 4270 with wood case recently sold for $1200.00. Without the wood case and unrestored they will typically sell for $500 to $600 depending upon their condition.

  1. I still own a 4270, and it is still working just fine. I bought the unit new in 1977, and also have 4 Infinity Quantum 1 speakers I use with it. The other components are just a combination of Pioneer(dual cassette deck), a JVC quartz lock turntable, and a Pioneer CD player. I love my system, even though it dosen’t match, but all works together just fine. The newest component (CD player) was bought in the early 90s. If it ain’t broke, don’t fix it, right?

  2. Doskonały dźwięk, determinuje w klasie takie urządzenia jak 2270 czy 2275,
    4270 zdecydowanie nie ma sobie równych.

  3. I inherited my 4270, with the wooden case, from my father-in-law. It required some work by my tech, and I upgraded the panel lighting with LEDs. I’ve never experimented with the quad mode. It performs very well with my B&W 220s and M&K sub.

  4. benny yo tanbien tengo un 4270 y no lo cambio por niguna otra marca siempre e sido fanatico de marantz no ay mejor sonido
