Is the DAC in my Meridian 861 good enough??

Hey guys i have a meridian 861 version3- Is the Dac in it good enough that I can just get a good transport or should I get a Meridian 808 or G08 to use- Strictly redbook but I do enjoy the music- thanks bill
I have a brand new Meridian 800 v4 since march 2005. Before that one I had a Meridian 800 v3. But the v4 is totally new in many ways. When you update teh v3 to v4 you don't have the same machine. The new verseion is a few steps better than the version 3. That means that Meridian made big improvements with the version 4. But I am not sure if they still use the same dac because the inprovements are quit big.
