Lively, fast & open sounding integrated under 3k?


My speakers are 89db 2 way monitors with a very warm sound. Minimum impedance 3.5 ohm
large Room, low level listening 

My goals
no.1
excellent immediacy, speed & timing (dont recommend naim, very unnatural forced sound)

no2
forward soundstage (begins at the listening position and extends beyond the speakers)

No3.
Body without warmth

no4.
small in size if possible, but no class D, doubles into 4 ohms, Good at low volumes
new or used.

possible candidates from reading reviews

Parasound stuff and the Halo have an incredibly clean midrange, they just do not have the high frequency extension that other amps do.
I think you may not like the sound of Class-A as that’s what the highs would be running as with the bias they have on them. As they sure are not rolled off as far as frequency bandwidth goes.

Parasound:
Frequency Response
2 Hz - 120 kHz, +0/-2 dB
20 Hz - 20 kHz, +0/-0.25 dB

About the same

was down by 3dB just below 100kHz!!

Sorry, but all amps pretty much have specs like this.  It comes down to listening.  It may seem to you that the high frequencies are not rolled off, but if you put the A21 side by side with something like a Krell Evolution amp, it becomes very apparent that the Parasound is lacking in high frequency detail.
As I’ve said I’ve heard the Parasound, and they do not lack in HF to me. Maybe you listened to a dud one.

As these are comments made on the highs, from reviews.
The sound was anything but mellow with the Spendors’ tweeters firing at ear level, but joined the Spendor’s crispness to the Hint 6’s wholeness and refinement. It almost felt as if I were leaning into the Trondheim Soloists’ performance of Tchaikovsky’s Serenade for Strings in C
.
Parasound never pushed the Quads’ ribbons into dangerous territory. Instead, music sounded brilliant and tangible, with a pulsating energy that made the strings of the Trondheim Soloists absolutely breathtaking. The sound was exhilarating. The Quads revealed the upper air of the Fitzgerald LP, with horns, hi-hat

Parasound was no exception. This combo was magical. The leading edges of voices, tenor saxophones, and drums reached out to caress my ears. A joyous sense of upper-treble air made all music exhilarating, transparent

There was something else wrong when you hear it.

I don't pay attention to reviews much anymore because they really don't tell you anything.  I have owned three different JC1 amps, one of them was brand new (and burned in 500 hours).  The A21 was also brand new.  I have owned a variety of different amps and have compared these Parasound side-by-side with other amps.
