Looking For Single Source Tube Preamp


My system is currently a modified Denon 5910 as my only source, a passive Luminous Axiom as my preamp (volume control), B&K Sonata M200 mono amps, and Silverline Sonata 2 Speakers. I enjoy the sound of this set up; however some of the discs I listen to come out sounding a little harsh. I intend on keeping this a single source system. I have never had a tube anywhere in my system. I was thinking of trying a single source tube preamp to possibly smooth things out a little. I have read some threads, but I can't find much on single source tube preamps. Is there anyone out there with a similar set-up to mine that can offer suggestions?

I am aware of the Decware Zsla-1 preamp; however I have not heard it or seen much about it on Audiogon.

I'm not familiar with your preamp or your speakers, but I've been running M200 Sonatas in many many different system configs - never any harshness. This includes using a Denon 2200 multi player as a source.

I think Nsgarch has given the best advice, but if you just want to experiment, the Dared 2000A is a 2 input tube preamp with remote volume. They show up on A'gon now and then for $300+ used with upgraded tubes, and I think can be bought directly for under $500 (or 450)

I have one and it's pretty nice for the $, and combines nicely with the M200s
If your Denon is the APL mod, then I doubt it is the problem. I have a very revealing system and there is no trace of hardness.

Space tech has great sound, excellent quality and reasonable pricing.
Space Tech Labs can build you a single input tube preamp at a very reasonable price. They sell multi-input models, but Albert will pretty much do what you want.
If you have a preamp now or if you have a volume control on the cd, you can get a Musical Fidelity unit that has nothing but a tube buffer. (I forget what it's called.) You can put it anywhere in the signal chain.
