Hi. Hope someone can give me some good advise.

I have had a Nakamichi CA-1 and PA-1 like forever. However, now I really need to connect HDMI and optical digital sources from my Cable box and Computer. (Using Totem speakers) What do you suggest?

1) Replace the preamp: Was looking at the Adcom GTP-870HD preamp. Any better suggestions?

2) Replace both. Why not save space? Was thinking the Adcom GFR-700HD receiver. Any better suggestions in this case?

3) Other options or considerations?

Thanks, Ty
