Which preamp for Symphonic Line Kraft amps?


Hi All;

I'm in the process of receiving a pair of Symphonic Line Kraft amps to power a pair of Dali Megalines (using a tube crossover). I'm currently using a Dodd battery powered preamp and am thinking about upgrading to either a Symphonic Line solid state amp (RG3 mk4) or the new CAT Renaissance (replaces the SL1 Ultimate mk 2?).

I'm guessing the best way to find out would be to use my ears if I can audition both units in my system, but these aren't items I can drive down the street to pick up...

Any thoughts would be appreciated though, especially regarding the SL preamps...

Would stick with either symphonic line rg3--ss or tube ---the CAT is also a great choice and I believe mates quite well
Jonathan_s,
you lucky so & so - a PAIR of Kraft amps! That should be -s-w-e-e-t-!!
Are you anywhere close to NC that I can drop in sometime to listen to (what seems an excellent) your setup??

which exact preamp really depends on your sonic taste. I've used the CAT preamp with great success.
A good friend of mine has tried out both the Erleuchtung & the RG3 MK4 (which he owns now). The Erleuchtung "lights" up the soundstage like only a tube preamp can. It is a bit light on the bass compared to the RG3 Mk4. Additionally, the Erleuchtung has a lot of tubes inside - each of the 5 inputs has a tube buffer, then 4 tubes for the line stage, 4 for the built-in phono stage. So, that adds up to 13 & I'm missing 1 tube somewhere - so total 14 tubes!
Both the RG3 & Erleuchtung mate very well to the Kraft amp - the RG3 has better (balls to the wall) bass.

I am in Houston should you ever make your way down to this part of the country...

I need 4 identical channels of amplification for the Dalis, so I needed 2 of the stereo Kraft amps. I'm guessing that I can't really go wrong with either a CAT or a Symphonic Line preamp, but I haven't really seen much on the web about the latter. I'd like to use a solid state amp and get away from tubes (it can get very expensive to use NOS tubes), but I'm not sure how much of a penalty would be paid to go to the RG3 mk4 vs using one of the tubed units.
Jonathan_s,
Thanks for the prompt reply.
I will certainly keep you in mind if I make it to Houston. My Dad's school friend lives there & teaches Pharmacology at Univ of Houston. And, I have another friend in Katie.

Indeed, you cannot go wrong with either a CAT or S-L preamp. If you get the CAT, as you well know, the tubes come from Ken S after they get thoroughly screened. They are current production & cost a modest amount. Ken does not believe in NOS tubes, as you know.
In the Erleuchtung you could use NOS tubes but I supposed well screeened current production tubes from a reputed dealer will be easier on the pocket-book.
The RG3 is supposedly very good sounding & I'm told should end your quest for a preamp.
The sonics of tubed vs. s.s. is a perennial & endless debate!! Hard to say what you would lose - everyone listens differently.
Jonathan,

The Kraft amp has a 10K input impedance and a high sensitivity. In my experience (very limited), you need a preamp with a very low output impedance, moderate gain (12 db or so), and dead silent. I have a Kraft amp and RG3 MK4 preamp. I did own a ARC REF3 for a while but found it lacking in bass, dynamics and it had a low level hiss that was distracting at night. In the end I gave up and resigned myself to trying the SL preamps. I have tested both the tube SL preamp and now the RG3 MK4. Both do the job. I have also heard of many state side Kraft owners having excellent results with CAT preamps. I decided not to pursue this because the CAT can have too much gain and then you hit the noise problem.

Good luck in your search.
