I have used my ZH270 directly with a SONY SCD1 and with a WADIA 850. I then bought a Pass Labs Aleph P and used it for a while. I now have a BAT VK30SE. I actually like using both preamps over the direct connection. The direct connection is of course more transparent. But, I think both preamps actually added some body to the sound. The Pass is a bit more transparent. But, I like the BAT better overall. I also need to switch sources; and like the convience of remote volume and mute.
You might find a VK30SE with phono within your price range on the used market. Earlier BAT preamps can be upgraded.
