Tvad's points are well taken. FWIW, Pubul57 came to the same conclusion after comaring the XA30.5 and the Amta-Sphere M-60 on his Merlins. I have been very impressed with the XA30.5 on my Geddes Abbey speakers. It smoked my hybrid amp. My speakers are 95db efficient, 8 ohm nominal impedance and have a reasonably flat impedance curve. Ralph Karsten of A-S reviewed the impedance curve and said these speakers are very well suited for his amp and recommended either the S-30 or the M-60. I bought a M-60 and will post my impressions after I have a chance to make a comparison. Having either of these amplifiers in your system is a problem of riches IMO.
pass labs xa30.5 vs aleph 3
Stereophile reveiwer Erick Lichte has done a head to head review of these pass amps in August 2009 issue. Erick uses the aleph 3 as his main amp feeding a pair or Revel f30 speakers, he also uses Benchmark Dac1 to feed the alpeh as I do as well. He was asked to do a comparison between the pass amps as a follow up to the great reveiw of the xa30.5 which was reviewed by Brian Damkroger in which,I quote "absolutely, positively,and enthusiasticallly recommended" the xa30.5 and, Brian sounds like he perfers high powered amps in the review. In the review Erick thought the Xa30.5 sounded more resolving and a little bit better bass control and can sound louder than the 30 watts. It was leaner in the midbass than the aleph 3 but, had a slightly more presents in the top three octave. he still is in love with is aleph 3 and sound like he is not planning on replacing the aleph 3 with the xa30.5. Anyways I have been waiting for a head to head review of these pass amps since the xa30.5 was released. If anyone would like to see the head to head review send me an email and I will take a high res pictures of the artical and send it to anyone. Also Erick Lichte did a head to head review of the Musical Fidelity's 550k supercharger amp and the Aleph 3 in a December 2008 issue. He concluded the aleph sounded better than the 550's by itself. He then supercharged his aleph 3 but did not like the sound. Very interesting articals about my beloved aleph 3, and a great read for aleph 3 owners. In my opinion the aleph 3 is still a giant killer and is a legend when it comes to amps.
