tube pre amp plus solid state power amps?


HI there,
My systems have always been tube system all the way through phon stage + pre amp+ power amps, but recently I got a little tire of maintenance of these amps and thought about changing power amps to solid state. I listen classical music. I always love tube amp particular from my LP collection. I am worrying about using solid state power amp will loose the texture of the sound that I like. However, I have done a little reading, some one said high end power amps will keep that sound, especially something like McCormack DNA-500 and Claytons amps. There are some writing confuse me, such as: “it is not important to use tube phon stage, solid state will be better.” I even read the statement says: pre amp is the least important of the whole audio chain.”

Well, what I am thinking about is keep tube system for both my phon stage and pre amp, use solid state for power amps replace tube system. Does anyone can tell me this will be a good change, or I need either whole system on tubes or on solid state?

Thanks

I think I understand your dilemma. I’ve heard from more than one person the Clayton amps give you more of the tube sound, but there are others which will too. The post on hybrid amps are a very good thought. Another couple to consider there are Butler & now Dodd Audio’s new one.

the thoughts on impedance mating are quite thoughtful too and very important.

I’ve found the most noteable diff from a tube amp to an SS amp is simple… impact & speed. Is that your goal? Is it worth it to you to sacrifice the voice of the tube amp to acquire it? Naturally if you are merely adding too instead of replacing, the aspiration is less important…. As then you’ll have both on hand for whatever mood you’re in at the time.

Each and every account of the thoughts you’ve so far read are all subjective ones. For those people only, they found such and such results satisfactory or not. Now you want to find out for yourself… and you should I suppose… if as I said, you seek more speed and impact, especially down deep in the bandwidth.

There is definitely no right or wrong way to go. No better or worse way to recreate the sound. You alone have to choose what’s best for yourself. Forget about perfect. It’s an illusion. Get what appeals to you… not someone else. The only way to know however is you must try it/them and decide… or just be happy with what you have now.

I’ve got a cheap but pretty good SS amp in my Odyssey Stratos Plus + amp. I’ve also got a Butler hybrid amp and a pair of Dodd mono block EL34 amps. Each amp has it’s own way of presenting the sound. I like them all.

For many types of regular use I like the combo of my tube preamp + the Butler TDB 5150. Overall it has no overt shortcomings. Plays every genre very well. It’s true strengths are in the bass and control of the speakers top to bottom. It has the ease and refinement of tubes, and the control and speed of it’s bipolar output devices… but not the decay or harmonics of pure tube topology amps.

In short, it doesn’t have the voice of the Dodd amps though. The Dodd MK II 120wpc monos are vastly superior to the Butler in the mids and upper end yet I prefer to use a sub when they are in play.

I do dig where you are coming from on the upkeep of the tubes being sometimes a chore. It always comes down to making a choice IMO… a compromise usually. Hybrids are a very good idea for those who want to try to bridge the gap from pure SS to tubes. Yet even with hybrids until (I suspect) you get well into the more pricey ones, like LLamm, BC, Moscodes newest version, Butler’s Monad, or Gary Dodds latest entry, they will always be a compromise… allowing for a taste of tubes only, but with better speed and control of the speakers.

Other considerations might be Wolcott, or the Pass x.5 series amps. Choosing depends on what you want from the amp and your squeakers demands for power of course… and then there’s the cost too.

AS far as I know it, a great tube preamp is only half the sound of a great tube preamp and a great set of tube amps. No more or less. Adding a SS amp will reduce the flavor by half just about. In your case I’d presume by a third as you also use a tube phono stage.

Very good luck.

Suikang, I think your "worry" is well grounded, I simply could never find an SS amp that would be my full-time amp, and I tried. I own Merlins VSMs that work extremely well with tube amps, and I suspect with some speakers, the high current, high power SS amps may be preferable to tubes - some speakers seem to shine with SS amplification - they need it. But, if you are hooked on what tubes do, I just don't think you will get that from any SS amp, as Tvad says, from any brand of SS.
It's not the same sound with a solid state amp. I have had the combination before. I'm used to a complete tube system and doubt that I ever could be satisfied with a solid state amp again. Some of my friends have solid state systems that sound excellent but they don't sound like tubes either. The maintenance is cheap and easy for me, one quad set of KT88's per year in the VAC and we're happy.
Yes, the hybrid tube/ss amp is definitely worth considering in this situation. Along with the brands already mentioned, there is Jolida, Vincent, and van Alstine.

I'm using the van Alstine Ultra 550 and it works very well for me. I think I'm sold on the hybrid tube/ss concept; tubes in the input stage, where they do their best, and SS in the output stage, where it does its best.
