I now have about 100 hours on my Raven and fell i caan objectively give a review. First my system; my amps are Quicksilver V4's, my phonostsge is a Modwright PH 9.0 XLT, my preamp is the Raven, my turntable is a VPI HW19 mk4. the tonearm is a Woody Stringe Theory with a Soundsmith MIMC cartridge.
The addition of the Raven has provided an unbelievable sound stage.
The highs are great as is the midrange. Thee bass is much deeper and clearer than ever before. These were the major things I was looking for and got with the Raven>
I also have an Oppo 205 and it also performs with all the positive things I have listed.. To elaborate a little more I was very happy that the soundstage spread out over my listening area. The real plus is the bass improvement. II is tight and quick.
All in all it is very musical and very enjoyable which i can and have listened to for hours at a time. I will say at this time this is the last preamp I will ever buy. I hope this helps in your decision making procees.
