What's a good upgrade from a Krell 300cd cd player

My 505 has two toroidal transformers. A true upgrade for the new drive. Krell did much more than slap a new transport in the mountain of broken Standards piling up at the shop. Eliminating an upgrade path is not typical Krell either. Don't get me wrong, I miss my Standard and will acquire one, completing my KAV stack. For critical listening, I will fire up my EVO. If they sound the same, I'll GIVE you whichever one you want. How's that.

I recently had the opportunity to listen to the Evolution 505 in an all Krell Evolution System, and it is a beautiful sounding (and looking) Machine. Zieman is right "it is in a different league than the Standard" (which I have owned).

I also agree with the others that in a non-cast system the 505’s prowess might be slightly diminished when directly compared to the very best one-box Players availabe – but in regards to this thread - for the money a used SACD Standard (preferably a MKIII) is a great deal and as good as is reasonably needed for most non-cast reference systems.

Jimmy, I have tried all the cast cables one can try. Cast can be outperformed. I've done it. It may seem crazy to invest more on cables than the machine (Tara Zero) but the improvement is once again an order of magnitude better.
