Amp for Dynaudio: Pass Aleph 3 is OK?

My system is Dynaudio Audience 60, Adcom GFP 750 , and NAD 214 power amp. Source is Cal Alpha and Delta combo.

NAD 214 has a power to drive Dynaudio(86dB, 4ohms), but it does not have dynamics and details.
I would like to replace my power to either Pass Labs Aleph 3 or old Krell (KSA 50).

I don't play music loud and listening room is also small, so I don't need a huge amps, but I want all the details and dynamics even at lower volume, and Aleph 3 has good reputation for its clarity. I am not sure if it can drive my Audience enough.

My budget is around $1500, but I can spend more if a couple of hundred dollars improve sound dramatically.

Maybe, I could go with an integrated amps. I tried Bryston B-60, and it was quite impressive for vocal and jazz, but the base was laid back...

Any advice is welcome!

Thank you!
My room is about 15x20. I just got an reaply from Dynaudio, and they said Aleph 3 could drive my speaker without any problem, but he added, "you can never have too much power".

interesting~~~

How much power does the Aleph 3 have? I would concur with Dynaudio's statement that you can never have too much power - the Dyn's love it! If you're willing to live with a class A amp (from a heat-generation perspective), the KSA-50S is probably an excellent choice, even at 50wpc. Another possibility would be a Krell KAV-250a - they're being discontinued and are therefore available used for $1600, give or take. Krell amplification with Dynaudio speakers is typically a great match (I have that amp and the Contour 3.0's). The 250 has (as you might guess) 250w/ch and doubles with each halving of impedence (so 500w/ch into 4 ohm speakers). While you can never have too much, you'll have plenty. I've never listened to the 60's, but when I upgraded from 100w/ch Krell to the 250, it was a very significant upgrade - everything was much cleaner and clearer even at very modest volumes. I don't know what the NAD delivers, but I'm not surprised the speakers sound a little lacking in the dynamics. You'll love the improvement whichever route you go. -Kirk

Kthomas-The Pass Labs Aleph-3 is a single ended, 30 wpc pure class A bias.It is a true class A and sucks 250 watts from the wall at all times it is fired up.It plays MUCH louder than a 30 wpc should.
Correct me if I am wrong,but I believe the Krell amps you mentioned arent a *TRUE* class A design.
IMO,the Pass is the better of those Krell amps.I have a friend that has a Krell KAV 250 and the Aleph-3 smokes it.Of course the Krell plays louder but thats the only area it beats the Aleph at. I even like the bass of the Aleph better.It sounds more realistic.I am more than happy with the volume I get with 30 wpc.As they say "its the first watt that counts the most"

Kthomas, the Aleph 3 is a wonderful sounding little space heater. If you live in a colder climate the sound from this little amp will not only warm your heart but your toes on a cold winter's night. The amp can drive the speakers you mention but I can not attest to what volume. It appears that David99 feels it will supply sufficient volume, so I will go along with him. In any case, I have heard this amp many times before and can assure you that it is one of the sweetest amps of modest power I have ever heard. Best of luch to you.

Thank you for your all postings!

I did not have any experience with Krell powers, but I auditioned 300i integrated amp with Audience 60.
Please don't mad at me, all Krell 300i owners. In my experience, I don't know why 300i is so expensive ($2500).
Yes, the base was slamming, but that was it. May be I don't like too much kicking base, but I love tight and dynamic base, but Krell's sound was little bit off.
I have heard that Krell's KAV250a and 300i shares the same power, so I expect similar result with KAV250a.
I don't know.............Maybe, just Krell's pre amp in 300i is just not my type. I better try with KAV250a.

The reason why I am considering KSA 50 as a candidate is that so many people say the Krell is the best match with Dynaudio, and it is around my budget.

Anyway, I live in LA, CA, and no dealer has Aleph 3 any more.

By the way, I am pretty impressed with Mr. Nelson Pass. Yesterday, I emailed the similar question to him ,and I got an immediate reply from him. I think he knows what he is doing, and he must be a sincere person.
