Phono Stage for passive preamp control

The gain issue is really important when using a passive preamp even with SS units. I would pick a unit that is adjustable in case you need to dial it in.

I have a Naim hicap/stageline that I love but really did not work well when I had my Rogue Tempest (great integrated but had passive line stage). Luckily Naim was able to adjust that gain slightly to make a big difference but I had to have them do it. Of course in this situation Naim presumed you are using an active line stage.

I use a Benz PP-1 and a Passive preamp with no problems, unless you want rock concert levels.

Might not the output impedance (generally high) of a tube phono preamp make trouble for a passive preamp? I know that Gordon Rankin of Wavelength strongly recommends an active preamp for use with his Tangent phono preamp, output impedance 1500 ohms. Caution on that score would be wise, I think. Anyway, others have given you a lot of good advice.

I'm not sure about units priced over 1K, but I purchased an Ear 834P and I'm very happy with it. It has close to 70dB of gain, and since it is a tube unit, it is very tweakable. There are many tweaking suggestions on this site and others. Some are as simple as replacing the stock tubes; others more involved. Most of the more expensive tubed units had 60dB gain. Most of the SS units, had more gain. I think the Michell/Trichord Delphini has over 70dB of gain. However, 70dB may not be enough for a cartridge with an output below .4mv with a passive preamp.

You should be able to get a used Aesthetix IO (the basic model) for around $2500. Tons of gain using tubes and sounds great. Designed to drive an amp directly with optional built in stepped attenuators but this will set you back a few thousand more. I use mine with a Placette passive pre and it works very nicely.

I previously had a Pass Aleph Ono that will be closer to $1200 or so and is a fine sounding unit, but not quite as good as the IO.
