Fosgate Signature Phono Preamp

Marlon and Reb1208...how would you describe the sonic attributes of the Fosgate amp? Marlon if you could compare it to the Moon LP5.3 with PSX5.3 power supply (I have heard that phono and so the comparison would be veryy helpful). Reb1208..also interested in your descriptions of the sonic attributes of this phono before and after tube-rolling. I am curious about this amp and don't have the opportunity to audition locally. Thanks very much.

Sonic attributes, I'll address regardless of tube compliment. To me, this unit sounds exactly like the circuit its built upon. Have you ever heard the clarity of a DC powered phono stage but wished it had a little more oomph? That's what you get with the Fosgate. A very clear, deep, wide open space that lets an unforced, natural musical flow come through. The signal path tubes are powered by DC fed from large storage capacitors. The power supply is fed AC and high voltage rectification is achieved by a 6X4 rectifier tube. That's where you get the extra little oomph, that's missing in other DC powered stages I've heard.

Rolling tubes, you can really enhance dynamic contrasts, bass punch, extend bandwidth and get the sound field well off the speaker cabinets. With the stock tubes, the unit leans toward a warmer and more relaxed presentation.

Being that this is an all tube unit, don't expect "stump" puller type bass response. So if your speakers are in need of some extra help in the bass, the Fosgate won't add that to the signal- it's a rather neutral and accurate piece. (However, the supplied 6X4 JAN Philips rectifier tube is well known to be softer in the bass. A NOS Tungsol or Raytheon 6X4 will definitely deliver more bass power) Ahh, but if you want to hear a drum kit sound realistic- this unit will give you that in a way that solid state can't touch. It's also quite capable of resolving low level detail, you may hear sounds and vocals previously unnoticed.

Thx for the feedback Reb1208.

Now using a NOS Sylvania BP 6X4 Rectifier and swapped one of the Tungsol 12AT7's for a BP Brimar 12AT7. Dynamics, bandwidth and bass slam beyond belief. Also, unit is now broken in.

Reb,
Don't you need to match your tube brands, V1,2; V3,4; and V5,6 to avoid
left and right channel discrepancies in gain as well as tone?
