Any point in adding tube preamp to SS integrated?

Good comments by the others, with which I am in general agreement.

But fwiw I'll mention that for various reasons, on several occasions with several different pieces of equipment, I have used a preamplifier connected into a line-level input of an integrated amplifier, and I have also used two preamplifiers connected in series, ahead of a power amplifier. In no case did I have a problem with overload or excess gain.

Typically I found that setting the volume control on the integrated amplifier, or the second preamp in the chain, to around 11 or 12 o'clock would result in the volume control on the first preamp being used in a reasonable part of its range.

The specs on the CAP101 don't indicate input overload voltage, and its overall (line stage + power stage) gain of 60.5 db (at maximum volume control setting) is probably a bit higher than average, but I still think you would be ok doing that.

Also, like some of the others my experience has been that a tube power amp is the most significant factor in achieving the benefits of "tube sound," but in fairness there are a significant number of others who have expressed the opposite viewpoint in previous threads here, claiming that using a tube preamp with a solid state power amp better preserves tube-like character than the opposite combination.

IMHO, Re the probability of the addition of a pre-amp adding extra gain and creating a gain overload, consider that the VC on the CAP would attenuate the gain from the tube pre-amp just as it would any other source - the worst thing that would likely happen would be you would lose a lot of the flexibility of the VC on the CAP.

A potential mismatch could occur if the tube pre-amp has a high output impedence as many do, but considering what you are doing it might well be benign. I wouldn't let the gain issue stop me for a moment.

However, as I indicated earlier, I don't think you will get real 'tube magic' anymore with this addition than you did with your buffer (a conclusion you may already have reached). But you bend the tone provided that the pre-amp you use benefits from using tubes which have greatly varying sound (like 12AX7's) and are cheap. I mention this only because I find a lot of folks think 'tube magic' has something to do with mid-range or lower mid-range warmth, high frequency 'sparkle' and a lot of other tonal issues, as opposed to spatial, liquidity, and proper decay issues which is where I think tubes can excel and SS often falls short.

FWIW.

The Classe' integrated is a fine piece of gear.... however if you want tube majic... sell the Classe' and get a true tube integrated like Manley... uses EL84 output tube and can be oerated in triode mode as well a ultralinier. Lots of tube majic there at a very reasonable price. There other good choices too. I would spend some time learning about tubes and the way they sound before making a choice.

Good Luck
