re: A-40

Tengo este amplificador desde hace mucho tiempo. Hace 2 años aproximadamente compré un Denon AVR 1611 usado, y solo suena muy bien con DVDs o Blu-ray con contenido digital DTS master audio, Dolby Digital, etc. No me satisface como reproduce audio de CDs. Voy a utilizar el manual de service del Sansui A40 para repararlo y continuar disfrutando de la calidad de sonido que este amplificador tiene para música en general, especialmente de CDs.

I have owned th Sansui A40 for many many years. About 2 years ago I bought a second hand Denon AVR-1611. I am only satisfied with the quality sound I can get form DVDs or Blu-ray with content according to DTs master audio or Dolby digital standards. I am not satisfied at all with the way it treat the digital PCM audio signal coming form a CD.
I going to use the service manual Ingot from this page in order to repair my Sansui A40 and start using it again for playing music form my favorites CDs.
