tube vs SS my own little test

So last weekend I went to a audio show at my local dealer. But alas the dealer was sick so. I a distributor filled in for him. I have know for a few years.

So we started chatting. Last few years I have been changing/upgrading my set little by little. Different speakers, turntable, phono amp. However my integrated amp stayed. My amp is a Symphonic Line La musica. So out of curiosity I asked him what do you think. I my amp still up to it.

To which he answered, I don't know. Why don't you borrow an amp from the shop and find out. So I went home with an Octave V110 and an Octave Super Black Box.

So how do they compare? Well the difference is different from what I expected. I have never owned a tube amp, or any tube gear for that matter. The Octave is a push pull pentode tube amp. This particular V110 comes with KT150 tubes instead of the KT120 tubes which the V110 normally has. Since I know nothing of tube I have no clue what that means to the sound.

Back to the sound. First I was disappointed a bit. It didn't sound that good. a Bit lack luster. And no "magical" tube mids that I have read about. The SL was more punchy, better controlled bass, and the mids and high were not that different.

However that changed after some time. Me knowing nothing of tubes didn't know that it can take up to an hour for the tube to completely warm up or something. because after about 30 minutes the amp sounds a lot better and after an hour even better still.

The SL was still a bit more dynamic and maybe still had a little more bass power. But after an hour the Octace mids and highs are clearly superior. Not that the SL is bad by any standard. But the Octave sounds more organic for lack of better wording.

But how practical is an amp that needs close to an hour to warm up? How typical is that of tube amps? Since to me I think it would be a deal breaker. I do not always have the time sometimes I just have 20 minutes.

Do hybrid integrated amps tube pre/SS power suffer from the same "shortcoming"?

Coming days I'll listen some more and see if I can find more differences.

If the amp had been sitting a while it may have taken a bit of time to form up the filter capacitors in the power supply. Prior to that the amp would not have sounded very good- that is a common experience!

In such a case if you continue to play the amp you will find that it does not take so long to sound right as the first time after its been sitting.

tubes worm up 5...10min after that no difference.
solid states at least half-hour.

Let state for the record that I have nothing against tube amps.

If I come across as anti-tube then my apologies. Some of the best audio I've heard used tube amps (Zanden, Octave, Jadis). But I've also heard very good SS (Symphonic Line, Pass, Boulder).

It might very well be that the times I heard tube amps under perform it might be bad amp/speaker match.

I have found that my tube and solid state amps and pre-amps need about 30 minutes to sound their best. (to me).

I turn the system on when I know I'm going to listen and go do something else for awhile.

Also, my preference is a tube pre-amp over a solid state pre-amp and a tube or solid state amp. However, this totally depends on the equipment auditioned.

If one was given the top 5 pre-amps (5 solid state and 5 tube) and top 5 power amps (5 solid state and 5 tube) in a particular price point range that could correctly power your specific pair of speakers, I would bet that you would be a very happy camper and you would have no problem going back and forth between equipment, regardless of whether it was tube or solid state.

But, back to the point, warming up equipment is really necessary to perform their best. Anyone telling you otherwise is trying to sell you something.

Don't let the oil get to temperature and flow correctly in your car and you will find that you will need mechanical work sooner than if you did let it warm up.

My system sounds cold (I know, not a great description), when not warmed up. But, when it warms up, it really opens up. Solid state and tube. no difference.
