I am a fan of Denon brand,I have a CDRW 1500 for many years.Yes is a very good cd recorder,...but also I ovned from Harman Kardon CDR2 and CDR30,and I must say very sure,"if you will have a best recording cd,use this CDR2 or CDR30 from Harman Kardon".I have compared also with Maranz DR17 and with some models from Philips.
You can use 4x speed and the quality of recording is extraordinary,(the better suport is MFSL Gold blank disk).
You can find second hand HK CDR2 with very litle price.If he have problem the laser head is Sf151 from Sharp /15 Euro,and another problem can be the power suply parts.
In another words,with 200-300 Euro in my opinion,you can have one of the best mod of posibil record.And....trust me,not matter what say some people about the PC recorder....forget this comparativ with a dedicated cd recorder lyke HK or Denon,Marantz....
