Rotel rsx 1058 or marantz mm8077

OP why spend several hundred $ on a used Rotel or Marantz when you can get a Quad Vena,Cambridge Audio Azur 841/851 or Audiolab M-One for around the same $ that will SLAY either of your two choices in every performance aspect?
These "Control Amp’s" have all the connections you need INCLUDING Phono Stage,Optical Input for TV,Analogue RCA & Coaxial Digital Inputs for CD Player & BlueTooth!!!
All will also scale up to much much much better speakers(up to about $10,000.00)when upgrade time comes which neither the Rotel or Marantz will do...

The asking price on both of these is $200.00 bucks ??  I can get the above from Cambridge for that price?? 

^^^ sadly no.When I googled the amps I got the retail pricing..A brand new Vena is $500.00,the Audiolab is $800.00...A used Azur can be found sometimes around $400.00..
To be honest if I were you unless your old amp is shot hang on to it and keep saving.The performance difference will be well worth the wait!
