Amplification Suggestions for Legacy Whispers???

I have wun my whispers with a Krell KSA-250 most of the time.
They do not require as much power as that amp gives them. I have also run them with a Classe CA-400 (A little more rounded out not as tunefull as the Krell. My favorite amp overall was
the Bel Canto SET 40 Integrated (40 Watt single ended). More than enough power and holographic imaging like you wouldn't believe. I also recomend 2 Vandersteen 2wq subwoofers ove the Legacy subs. Subwoofers make a world of difference on the Whisper.

Any of the Plinius would sound good.

If you can find the Legacy monobloc or Ultra monobloc I would recommend auditioning them. I previously used a Classe CA-200, two channels of Aragon 8008x5 and also vertically biamped them using 4 channels of the Aragon amp. The sound of the Classe was too rounded for my taste. I always thought the Aragons sounded very good and biamping gave the best results with them. A couple of months ago I came across a pair of the original Legacy monoblocs and bought them. I had read about people feeling that the Aragons having a slightly grainy high end and I could never hear this effect. Once I hooked up the Legacies I realized they were correct. I guess you can't recognize this until you have a direct comparison. The difference was subtle but very definitely there and made the Legacies more musically satisfying than the Aragon. I also preferred the Aragon over the Classe. I could never get past the differences in the bass performance to keep it in my system. I felt the big difference in bass performance outweighed the Classe's slight edge in high frequency performance. The gap widened when the Aragon was run biamped. This is just my opinion and I liked the Classe enough to keep it for use in a second system.
The other big difference and what clinched it for me was that the Legacies require very little warmup time and run very cool while the Aragon requires about 30 minutes to reach its optimum operating temperature and sound their best and they generate a significant amount of heat. I generally don't want to play my system for 30 minutes before I listen to it. The Legacy also has a slightly darker tonal balance with great bass control and pitch definition. They also give a nice presentation of timbre and pitch of indivdiual instruments. Imaging three dimensionality is also first rate.
If you get the chance to listen to the Legacies with the Whispers you will not be disappointed.

I just got the Coda Stage 3.3, ei Legacy Powerbloc2 amp, to drive the Whispers. Rated at 6ooW in 4 ohms, it's a perfect match for the Whispers. Also using Kimber 8TC shotgun bi-wired.

If you haven't gotten your amp yet, I would suggest you listen to Steve McCormack's DNA-500. That's what I'm using on my WHispers and the sound is amazing. Lots of power and current (500w -8 ohms/900w-4 ohms),very musical, loads of detail without being fatiguing and very "involving" - it draws you in to the music. Tight bass control is also another characteristic.

In fact, even if you HAVE already gotten your amp, if its not the DNA-500, you might want to audition it anyhow just to see what you are missing!
