Nice review, Ferrari. I have always wanted to read a private review about this amp. I look forward to reading from you the follow-ups on its performance throughout its break-in.
Review: Marsh Sound Design A-200s Amplifier
Category: Amplifiers
Since I have had the Marsh P2000 pre amp for sometime and have found it to be all that TAS raved about, I was waiting for someone to post a review on one of their power amps. So this looks like the first on the Marsh Sound Design A200s on Audiogon.
I have this unit on evaluation from a local audio salon for the next 30 days. I need another amp like I need a case of the flu. This unit was not a trade in, the original owner fell on hard times and needed cash in the worst way. But nonetheless wanted to try the Marsh amp and see if it lived up to the TAS review.
I have only had this unit powered since late Friday June 4 so in all likely hood this review is somewhat premature and will post a followup after 30 days.
Powered down the Forte 4a and inserted the Marsh A200 into the system and let the Marsh A200 warm up for over an hour. In some ways comparing a Pure Class A amp to Class A/AB is like comparing apples to oranges, but most all my amps are Pure Class A output. But have to start somewhere.
First music put on using the Classe CDP.5 player was the album from Dotsero titled "Out Of Hand". The Saxophone and Guitar work jump to life,perhaps to much for my taste was a bit forward with some grain on the Saxophone. But was quite listenable. Soundstage was very good.
Next up was more Jazz this time from Bob James and his album "Restless". Usually piano music is a good litmus test for any amplifier. The Marsh A200s did very well indeed and captured the performances quite well. The Marsh combo has a very black background indeed and the music literally comes to life. Still a bit forward, however the grain was much less on this recording or the Marsh A200s is really stellar in this area. Soundstage remained good indeed.
Lastly played the CD from Hiroshima titled "Urban World Music". Chose this disc because of the wide variety of instruments and tonal qualities this group uses. The Marsh A200s really delivered on this album and it was somewhat of a shock compared to the previous music. Still the presentation was a bit forward, still a tad bit grainy on some of the instrumets.
Overall at this point the Marsh A200s is a very good performer indeed. Although it cannot match the Forte 4a in overall presentation,liquidity,transparency,detail, and depth of sound stage. For a Class A/AB amp it is very good indeed but in my opinion falls just short of the Muse 100.
But one has to keep in mind have only had this amp powered for about 42 hours now and the sonic signature can change with further use. I know the Marsh P2000 preamp I have has really come into its own, but took awhile to do so and 30 days may be not enough time.
Next week will test it against the Muse 100 as this will be a test of Class A/AB amplifiers head to head.
If any of the Audiogon Membership has additional first hand information of the Marsh A200s,I encourage you post to this thread. The more info the better.
