It's all up to you. In your original post you said you wanted a "warm" tubed preamp with remote. Neither the ARC or the Quicksilver will give you that warm tubed sound, IMHO. Are they very good preamps? Yes. Are they warm and tubey sounding? No.
If you want warm and tubey sounding preamps, look for Cary or Conrad Johnson. They are not my cup of tea, too warm for me, but I know many who like them, and that seems to be what you want.
