Just give it your best shot. Pay attention to input impedance of your amps- some tube preamps can't handle input impedances much below 30K or so! There are tube preamps that can handle low input impedances in amplifiers with no worries.

A Freya pre-amp used ahead of a Merrill Audio Taranis Class D power amp sounds great to me. The Freya (4-6SN7s) replaced an Opera Reference 50 (dual-6H30/EZ80-rectified) pre-amp. Both pre-amps worked just fine but the sound with the Freya is more refined...detailed but relaxed at the same time. The Freya is very flexible offering singled ended and balanced inputs and outputs as well as pure passive, JFET buffered, and tube gain output modes. It's very transparent and readily shows differences in tubes and interconnects. It is also being used with a First Watt F7 amp and a Hegel H200 integrated when used as power amp. What sorts of things related to use with Class D are you wondering about? |

@owentdc Hi Ralph. I had the UV-1 on loan after it first came out from Alternative Audio in Dundas, Ontario. It fed the power amp of my W4S STI-1000. We couldn’t track down the buzz and I took it back. Too bad, it did give a slight tube sound that I was looking for. We’ve found that the UV-1 can be sensitive to power cords. We had a customer recently that ran into this. While all the data isn’t in, he found that by simply moving the cord around, the preamp got quiet. |
