Another preamp question...recommendations wanted

Recommended Posts

I have searched the archives and did not find an answer to my question, so here it is:

I am looking for suggestions for an active preamp with the following features:

- low gain, say 10-12 dB or less.

- 2 pair of outputs (mandatory, as I don't want to use a Y connector)

- tube or SS

- at least 3 inputs

- quality sound (obviously)

- used (< than $500) or new (< than $1,000).

- phono stage not needed.

- remote optional.

Thanks,

Scott

After looking at your requirments, I think the 6SN7 based Wright Sound WLA-12a preamp fits almost all the qualifications. It has two pairs of outputs, switchable gain on the unit with a low of 12dB. It employs tube rectification and can be customized by George Wright for additional needs.

It has a stereo/mono/reversal switch too, another rarity.

I have heard this unit more than a few times in several systems and say it's an EXCELLENT deal either new or used. You see it pop up used on Audiogon for around $550-600 (new around $800). I rank it as a VERY relaxed, natural, detailed, open sounding preamp.

To all (Kelly particularily),

Thank you for the info on the Wright. It appears that low gain preamps are a bit uncommon, although they seem (to me at least) to be a natural choice for use with sensitive speakers. I use a pair of Chorus speakers and a VMPS larger sub in my system, which is my reason for a pair of outputs. I like having useable control through my volume/attenuation knob of more than 1/4 rotation.

Just for info, my web research has turned up the Grounded Grid preamp by Bruce Rozenblit (Transcendent) as a low gain, single output pre. In searching his builder archives, it appears that his and other preamps could be set up with dual outputs if I wanted to go the DIY route.

BTW, can anyone define what unity gain means?

Thanks,

Scott
