Well ,certainly If you have Rowland 8Ti the Krell won't be an upgrade.If you have Rowland , I'd try Spectral and then I would go straight into Goldmund say Mimesis 28 Evolution or a big one Mimesis 29. You can e-mail me with any questions :-)
Rowland 8ti or Krell FPB600c
Own Rowland, but looking for upgrade. Any suggestions please.
