Best Passive Preamplifier's


How do the best Passive Preamplifiers compare with the best Active Preamplifiers? Are the differences dramatic or subtle?

Why buy the active circuit in the Adcom when you're not going to use it? Instead, you can get a $60 ladder attenuator at s/one like these guys. Buy a box, input connectors, connect the above & you're in business! You'll have to check the impedance synergies of course -- but the vendor can surely help here.

Otherwise, and if finances permit, go for a TVC.
Creek and FT AUdio are the inexpensive Passives around. I have an FT Audio and I can say it is probably better than anything under $1k in an active.I put it against my Rotel active and I would not go back to the Rotel.

Placettes are suppost to be good if not better and Bent has been getting some great reviews.

Happy Hunting!
The Silver Rock is amazing. Its one of two components I have yet to be able to part with.

If from a technical perspective, you have no system matching issues, a transformer based volume control is often a straight up eye opening experience the first time people here it in a system.

As for actives -- there are some rather impressive ones out there. But those designing them usually have different perspectives -- some are purposely looking to 'give you something' with it -- some are particularly trying to maintain the elusive neutrality.....while adding an entire different interface and active stage between source and amplifier.

Sometimes that adding something is nice, sometimes its not, but its really worth a shot to get a TVC and see how it works in _your_ system.

The complaints I've heard most of the time really sound like poor system matching (technical), while occasionally I hear what sounds like poor system matching (synergy) -- where you see a system and go, why on earth would you want a source that horrible passed direct, and to an amplifier that will sound horrible? In those cases, I'd highly suggest an active, a colored active, and something that functions as an embellishment engine.

At the same time there are some folks who clearly know what they are talking about, and did not like the effect -- just a preference.

I'd see if you can get one or the other, and whether a visit to a dealer, or someone in your area, try them side by side -- it won't be something where you'll be trying to search to find the differences....

Leave me an email if you would like further ramblings -- I tend not to reply to threads once they disappear from the 'New Today' page on Audiogon..
The best active pre's can be better than passive. The placette passive is one of the best yet owners of the placette active who have also had the passive in their systems report it to be a little better. The difference could only be subtle unless the source/amp/speaker was bad match for passive. I have a Bent audio transformer volume control which is as good as the placette in my system. These two passive unit's are around $1200. I have read that the silver rock passive is one of the best but cost is much more. The thing I like about passive units is the hash they remove from the midrange that most active pre's (tube and SS) put there. For a person building a system, who has not yet bought his source/amp/speakers or the person who already has, but is lucky enough to have good match for passive it can be a very good thing indeed.
