Tubes vs Solid State - Imaging, Soundstaging, 3D


I have limited experience with tubes having had a couple tube amps with Gold Lion KT88s and EL34s. The majority of amps I have owned have been solid state. In my experience, SS always seems to image more sharply and offer the deepest, clearest field.

Is this common?

What JMCgrogan2 sez, except in my experience some power tubes are more linear in tone than others. With those more 'linear' tubes, such as the GL KT88's or SED 6550's I would agree that small tubes can make a greater difference than the two power tubes would make on their own. But with the SED KT88s, which are not so linear, i.e. increased upper bass and extended highs, small tubes matching is essential, as is amp matching. I've used SED KT88s as well as SED 6550's, SED EL34's, and SED 6L6GC's for some years and while I really enjoy the KT88's when they work (as they do now in one of my amps) as often I've not been able to dial them in using other amps, especially those with a more modern design ('neutral' tone, such as ARCs etc). I know nothing about your amps but I didn't care for the KT88's at all in my Cary mono's, but found the 6550's quite acceptable.

If you want a crystal clear toned linear tube, if you can use it, you might find the SED 6L6GC to your liking. It lacks the power of the 6550/KT88 and the mid-range warmth of the EL34, but it has clarity in spades through out the FR.

BTW, what kind of speakers are you using? Do you feel you have maximized your set up opportunities so that they are positioned to sound their best. In a 'dark' sounding room I can imagine that a tubed amp/speaker combo might sound less energized and a SS amp sound better, especially if you speakers are voiced on the warm side of neutral.
I suspect we all listen for different things. My experience has been that tubes and solid state do different things well at the lower end of price then struggle to converge at the higher end

Solid state has dynamics, biting detail, can rock the house
Tubes have mid range rectitude, vivid tone colors, can make you weep with the emotion of sung story.

To be honest image is the last thing I listen for; what good is a razor sharp spatial location if the instrument doesn't sound real for tone color, like its in the room with you. If that's right, image seems to follow at its heels
Having used Tube based preamp(s) for years, and in general having avoided like the plague the notion of Tube based power Amplifier(s), I got a bit of an awakening recently.

My reason for avoiding Tube based power amps are all the standard reasons, maintenance, heat etc.etc.

A perfect storm recently occurred in my life and for whatever reason I decided to replace my ss monoblocks with tube based monoblocks.

I was literally shocked at the difference! I would never have guessed that in 2013 there could be this much variation between great SS and great Tube electronics.

Different strokes and all, so I'm not even going to enter into any kind of tube/vs ss and which is "best". suffice it to say I strongly prefer the tubes. Others could and I'm sure would prefer the SS.

Personally, I see NO downside whatsoever to the tube amps. (other than of course heat, but my old SS amps were high-bias, and they threw a fair amount of heat also) Bass, imaging, focus, balance, depth are all as good or better in the tube amp. And, there is simply as one would expect FAR more what I call "harmonic richness" to the music. Call it euphoric coloration or whatever you want, the tube amp simply adds and/or extracts more meat on the bones of the music. Violin is a perfect example, it's a different instrument all of a sudden.

The added tube "lushness" would I thought always come at the expense of some level of detail. Not in this case, These are razor sharp, with no added harshness.

Just my own personal 2cents worth, I only wish I'd have done this years ago!
Hi Michaelkingdom,
Keep in mind that you may just simply prefer SS amplifiers as some others
do. Don't forget that the particular speaker in use plays a major role
regarding amplifier compatibility. My experiences are very different from
your own, I found well designed tube amplifiers to be as transparent, clear
and resolved as any transistor amp. The advantage I discovered with tubes
is a purity, natrualness and realism that the transistors couldn't equal.
Tubes have the tonal vibrancy and truthfulness that were closer(not
identical) to the real thing for me. With the many transistor amps I've heard
I was always keenly ware the sound is reproduced and a bit more artificial
("canned"). The tubes were more convincing of reality that I
consistently hear with live instruments and vocalists.

As with what Islandmandan said, the SET amps took the tube convincing
realism to an even higher level, I fully understand what Dan is presently
appreciating. The point is each of us will have differences in hearing
perspectives and interpretation. Some will relate to my personal listening
experiences and quite naturally others will not.
The suggestions given here to try various types of signal and power tubes
is wise advice. You can substantially change a amplifier's character and
sound by doing this.
If SS amplifiers continue to impress you more tht means you've found your
direction and that's the route for you.
Best of Luck,
