Hello. New to the forum and I had a few questions. I did do some searches to see if these threads already existed but I didn't find them. That said, if I missed them and I'm being redundant. Apologies.

I recently inherited a set of Fostex 206e drivers in the recommended horn enclosure (this enclosure design is older and I will eventually build different ones). I paired them to an old T Amp with a dedicated power supply and to my untrained ears the setup sounds pretty decent. Despite the drivers being over 15 years old and the T Amp being nothing special, it blows my Bowers and Wilkins Zeppelin setup out of the water in terms of detail and soundstage to my untrained ear. Also despite the low wattage, I barely have to set the volume on the T Amp past 30% to be too loud for the room.

I've gone ahead and ordered the updated drivers with tweaks from Planet 10 HiFi. So now I want to understand the best steps to take re:amplification.

The Stereomour II is not out of the question budget wise, but it will need to wait until the end of the year. My question is - having the components I have, how do I make this system "complete"? Will buying a cheaper kit and pairing it with the T Amp be a good solution? Do I wait and get the Stereomour? What else needs to go along with the Stereomour or is it enough by itself?

Ideally if the Stereomour is the best route, can/should I get some kind of preamp or other component that can work together with the T Amp now that I can later pair up with the Stereomour (I know the Stereomour is integrated, but bear in mind I know nearly NOTHING).

Open to advice. Much appreciated.

Martin.

Hello Martin,

You are quite wise to gravitate towards the Stereomour.  It is certainly the best choice for what you're looking to do, and it will be all that you need if you listen to digital sources or already have a vinyl rig with separate phono preamp. 

Being an integrated amplifier, the Stereomour doesn't strictly need a preamp in front of it, though we have had several customers use a Quickie or a Smash in front of the Stereomour for a little additional gain and to get that coveted preamp output as well.  This is certainly an option in your case, and using the Stereomour with a premap just requires that you turn the volume control on the Stereomour all the way up.

As always, we are here to help as you consider all the possible setups along the way.

Thanks. Can you explain why the preamp input is coveted? Also is the order Source > Preamp > Amp > Speakers? I would have thought that you'd control the volume at the amp?

Also, the smash being around 500 and the price difference between a base stereomour and the fully upgraded one being the same price can you tell me whether it's worth spending that 500 on the upgrades or the preamp initially?

Thanks again
Martin

Martin,

Welcome. You've come to the right place!

I recommend that you do it in steps. I wouldn't buy a pre-amp unless you NEED a pre-amp with the Stereomour. I'd try it by itself in your system first. If you find yourself turning the Stereomour up all the way and still not getting the volume you need then considering a pre-amp should be your next step.

Tip - All of the Stereomour upgrades are excellent. The shunt regulator IMHO is the best bang for the buck. Then the stepped attenuator. If you find that your speakers hum a bit at low or no volume then get the DC filament upgrade.

I hope this helps.

Tom

Yes, that's what the chain would look like.  When a preamp is used, one if its tasks is volume control. 

Also, the smash being around 500 and the price difference between a base stereomour and the fully upgraded one being the same price can you tell me whether it's worth spending that 500 on the upgrades or the preamp initially?
I would recommend the Stereomour and its upgrades over a base Stereomour and a preamp.  If you need preamp outputs for an active subwoofer, then the preamp can be very handy, otherwise the Stereomour on its own is going to fulfill your needs.
