How would the 302/402e series compare to their latest Duo line? If you know of course.
Move from Parasound A23 to A21/A21+ or Something Else?
Hello, looking for some advice on an amplifier upgrade. Some years ago I was able to get an original Parasound A23 for a really great deal. I like the amp quite a bit and it was a wonderful upgrade from a class d amplifier I was using. I am mostly happy with the amp but I have noticed on loud or complex passages that the music can become strained sounding. It will shift from a nice layered and smooth sound to a more brittle and flat sound. It’s like the soundstage collapses to one dimension right between the speakers and music gains a hardness to it. It’s hard for me to explain exactly as I not that great at descriptors for audio.
Anyway, it doesn’t happen all the time only when listening to dynamic and busy music at higher volumes like 85+ db average at the listening position; about 3 meters from the speakers. The room is around 4500 cubic feet and semi open to other rooms. The speakers are Focal Kanta 2s. When I calculate the actual needs for wattage based upon distance and sensitivity, I "should" be fine with the A23. However, I wonder if a more powerful amp would help with the issue?
I like the signature of the Parasound so I am thinking of a used A21 or maybe even the A21+ if I could snag one at a good price. Is there anything else that should be on my radar? Looking to spend up to $3K max, less is better. Or, I could save up and maybe get a JC5 in 9-12 months if it was really worth it.
Open to thoughts and ideas.

Hello @christianb5s4, I can say the amp has broken in nicely and I am liking it more everyday. The grain has smoothed out and the amp sounds much more balanced than out of the box. How would I describe it with the Kantas...it is detailed without being analytical. It tends to project the sound into the room more and put the listener in the front row where as before the sound seemed to come from behind the speakers and I was sitting many rows back. This projection threw me off initially but I have become more appreciative of it as the amp has added a great sense of depth to the soundstage. One can tell that the dummer is behind the horn player now on a given recording if that makes sense. A couple of other cool attributes, the amp has brought out a lot more micro details in recordings and I am hearing things I’ve never heard before on familar material. Another thing I like is, it’s all there even at low listening levels. I really don’t need to turn it up to hear more into a recording but if I do, it just gives me more of the same and never falls apart. The character doesn’t change with increased volume. It’s a great sounding amp and very neutral where as the A23 was slightly warmer. Anyway, I hope this helps and good luck. |
@christianb5s4 IMO Krell is a hit and miss company. The EVO line are first class regarding built and sound quality that includes the matching preamp Evo 222. I have not heard the current Duo line but the build and parts quality are not on the same level. Many Krell fans love the FPB line of power amps but most of them are pushing 20+ years old with multiple owners. The EVO line is in that 10 year old window where a 1 owner mint unit is still possible to locate. |
The new Duo lineup from KRELLL seems very well built. I have had the K-300i and now the 175XD and cannot fault them operationally. In fact, the K-300i was the very best implementation of ROON READY that I have tried because it also controls volume. On a lark I tried my KEF LS50's with the KRELL 175XD and what a great sound. I always felt the LS50 (the original one) scales with better amplification. My Benchmark AHB2 and this KRELL Dou 175xXD (very different sonically) really take the LS50 to great heights. I am going to keep this combo with a KEF KC62 sub in my small office. |
