"All In A Mouse’s Night"
I took a somewhat different approach from some of the other reviewers. I decided to use only one set of speakers, one source (my venerable Yamaha CDP) and the diminutive Mouse with its companion (and heavier!) 30V Power Supply. The equipment specifics included (NO separate pre-amp):
Yamaha NS-20T (Consumer version of the NS-20 Monitor)
Yamaha CDX-900U (My venerable CDP—the drawer is slowly failing--hence the popped-top)
I also, for comparison, switched between the Mouse and a McIntosh MAC 4100 with all controls set to “flat” (including the variable loudness). The NS-20T speakers are fairly small speakers with 8 inch cloth surround woofers and 1 inch dome (not Be) tweeters. I purchased these speakers about a year ago from Merrylander and I am frequently surprised at the fullness of range and clarity that these speakers possess. I also listened to recordings that I am quite familiar with, so I think that most of my impressions are fairly objective. With some of my favorite recordings I did perform side-by-side comparisons to confirm my gut reactions when listening to the Mouse.
My initial impressions of the Mouse were that it’s quite strong and capable; quick to react; able to handle dense program material (with clarity), yet a bit shallow in the lower-end, and at times it seemed a bit “boxy” in the low mid-range (lacking some of what I call “presence” or depth). But for sure, this little amp can really fill the speakers with clean and powerful output. In my listening room (about 12 by 16 feet), I found that with most recordings the volume control could go no higher than about 11 o’clock. I found this amp better suited for recordings with acoustic instruments, the human voice and percussion. For some strange reason, snare drums in most recordings seemed to present themselves quite forward in the output. This amp might work quite well with a powered subwoofer. Also, I could see this amp used even for applications such as large pleasure boats (not that I have a large boat, at all!). I'm sure that adding a pre-amp with tone controls would likely improve the low-end response. My listening included:
Genesis – Wind and Wuthering
-All In A Mouse’s Night (How could I NOT start with this?!)
“Then comes this monster mouse
It’s ten feet tall
With teeth and claws to match
It only took one blow!”
This is a VERY dense recording—full range. The amp handled the dynamic changes quite capably, but the closing with Moog Bass pedals was a bit thin.
Steve Hackett – To Watch The Storms
-Circus of Becoming – This is a curious piece with an Optigan, groaning guitar and a bridge with a simulated church organ and pedals. This was reproduced quite well.
-The Moon Under Water – Very well reproduced, but just a wee-bit thin in timbre; this is a classical/nylon guitar piece. Good, solid and clear output...this was one of the pieces where I really increased the volume control to about 2 o'clock trying to get the peak light to spike, but no go--the amp remained VERY solid.
-Serpentine Song – One of my favorite pieces ever by Steve Hackett. Quite a few vocals (harmonies), keyboards, a stunning flute solo by John Hackett and one of Rob Townsend’s best ever soprano sax solos (NOT! Like Kenny G)—as beautiful as a Mel Collins solo on a Clannad piece entitled “Soul Searcher”. The little Mouse handled this piece almost flawlessly.
Maire Brennan (of Clannad fame) – Whisper To The Wild Water
-From Where I Stand – A very full, lush vocal piece with light acoustic guitar interlaced with a synthesizer bass line. The Mouse reproduced this quite well, but it was a bit thin in the bass line.
Michael Franks – Rendezvous In Rio
-Chemistry Of Love – This is a Jeff Lorber produced piece—slow, jazzy, great dynamic range. The Mouse performed quite well, but was a bit weak in the bass line…I could hear it roll-off in some passages (and it wasn’t the speakers). I compared this with the MAC4100, and the bottom-end was fully restored.
Michael Franks – Dragonfly Summer
-Soulmate – Another Lorber produced piece—same results as above.
-You Were Meant For Me – The Mouse reproduced this haunting acoustic duet (with Franks and Peggy Lee—one of her last recordings) quite well. I love this piece--nylon guitar, acoustic bass, drums--alto sax solo.
Nick Magnus – Inhaling Green
-Inhaling Green - Part Two – Stripping The Flesh – an exceprt from a 16 minute piece from my friend Nick. At this point in the piece it moves into a rather droning “house” rhythm with an ethereal vocal. It reminds me a great deal of the sequence from the movie “Contact” (with Jodie Foster) where she is time-travelling. This recording has a HUGE dynamic range (very little compression)—and the Mouse held its own quite well. Again, only weakness was a bit in the low end.
Kraftwerk – Tour De France – Soundtracks
-Aero Dynamik—a real pulsing gem of a piece. Unfortunately, the low-end just about completely dropped out.
Scritti Pollitti – White Bread Black Beer
All of these pieces on this CD are VERY hot recordings with an enormous frequency and dynamic range. I was quite surprised that most everything was very well reproduced (except the REALLY low synth-bass lines).
-Boom Boom Bap
-Throw
-After Six
-Petrococadollar
Peter Gabriel – Up
-Growing Up – Unfortunately once this piece really got rolling most of the bass line was lost (but the MAC 4100 brought it back).
George Strait – It Just Comes Natural
-Give It Away – An excellent tune! Most of the tune and depth was VERY well reproduced. A bit of the bass line was lost, but it didn’t really affect my enjoyment of this great song!
Gordon Lightfoot – Salute
I love this album—beautifully recorded, clear and one of Gordon Lightfoot’s best of his later career. These pieces are three of my favorites. All three were quite accurately reproduced, except a bit of the woodiness (timbre and depth) of the acoustic guitar in Tattoo seemed to be lost in the output. I compared it to the MAC4100 to confirm, and back that depth came.
-Knotty Pine
-Biscuit City
-Tattoo
I found that there are many similarities between how this amp sounds compared to some small EL84 tube amps that I have heard over the years (very clear in the highs and mid, but somewhat weak in the low-end and depth). A couple of other observations: 1) There was a noticeable upper-range “pop” in the speakers at power-up. & 2) The amp was a bit noisy (hiss, but no hum) in the background when there was no source present.
Thanks very much for the opportunity to review this VERY cool little amp. Throughout my entire listening (most of this afternoon), it never skipped a beat and barely heated-up. Never once did any warning lights activate. Off to its next destination!!
