amp or preamp to extend upper end

Try turning the high frequency contour adjustment on your 3's up 1db.

+1 (meaning that I agree with ZD's suggestion, as opposed to suggesting that another db be added to the 1 db he suggested :-)). I took a look at John Atkinson's review of the Vandersteen 3 in the March 1993 issue of Stereophile. He states:

Although I found that the tone-control settings that gave the flattest measured response were HF -2dB, and MF, + 1dB, this sounded consistently too dull. I ended up setting the HF control either at 0dB or +1dB for most of my listening.

He also mentioned that the woofer and mid-range needed to be worked hard over the course of a very extended break-in period before they sounded good. If by any chance your speakers weren't used a great deal around the time of the transition between amplifiers, perhaps some re-breakin is necessary, possibly contributed to by age-related stiffening of the surrounds, or some other comparable effect. Keep in mind that the crossover between mid-range and tweeter, nominally at 5 kHz, is first-order, meaning that the mid-range driver will be receiving frequencies at significant amplitudes well into the top octave.

Regarding the other subject that has been addressed in the thread, FWIW my perception in recent years is that in initial quality surveys and long-term user satisfaction surveys, while most of the big-name German manufacturers seem to place not much better than the middle of the pack among all manufacturers, Porsche is just about always at or very close to the top, even though recent models are loaded with all kinds of high-tech electronics and other such things. Also FWIW, my 2014 Cayman S has been all that my wife and I had hoped for when we purchased it about a year and a half ago, although for many people its two seats, very limited cargo capacity, and stock high performance tires that can't be driven on snow or ice would rule it out as a practical choice. And no doubt any repairs that may be necessary after its 4 year warranty expires will not be cheap.

Rleff I did try almargs suggestion and it actually helped. Although I only had to go up by about 1/2 db.

Good! For the record, though, my suggestion essentially just seconded a suggestion that was made earlier in the thread by ZD542.
