Another well done review, thank you!
Review: Pass Labs XA60.5 Monoblocks Amplifier

The Pass XA60.5 Monoblock Amplifiers
Background:
I had been running the Pass XA30.5 Stereo Amplifier for about the last year with this System: Tyler Acoustics Decade D1 Loudspeakers, Ayon CD-2S CD Player, Jeff Rowland Capri Pre-Amp. The Tyler Acoustics D1 Loudspeakers are 8 ohm and are fairly efficient and the Pass XA30.5 did a wonderful job driving them. The sound of the XA30.5 is something special for a solid state amp. I would define it as very smooth from the highs to the bass and the mid-range is what distinguished it in my mind. The voices seem to be right there in front of me with so much realism and feel that it seemed the musicians were there in my listening room (also my living room). Well, I made a change from the Tyler Acoustics Decade D1's to the Tyler Acoustics Woodmeres. The Woodmeres are four ohm loudspeakers and they each have two seas 10 inch bass drivers. They may have similar sensitivities to the Decades but they are a larger load to push. I found that the Pass XA30.5 gave me that same midrange with the Woodmeres but was lacking some punch, especially on passages that were dynamic. Then comes the big debate! How does the Pass XA30.5 Stereo Amp compare to the Pass XA60.5 Monoblocks? I made a post on Audiogon and got a wide range of responses. Some people told me that they felt that the difference of 3 db would not make that much of a difference in my system. Many people seemed to feel that putting the money into the monoblocks was not the way to go. Some other people talked about that I was underpowered for the speakers I had. Someone suggested that I think about more efficient speakers. Anyway, I got a variety of responses.
The Real World:
The real world answer that that you don't know how anything is going to sound until you hear it. We can speculate all we want about how we think a particular component is going to effect our systems but until you hear it, you really don't know. I have said it many times but the biggest issues in most systems are the rooms the systems are in and the secondary issue is the synergy or lack of between the various components. I have been down the path myself many times worrying about how a cable change would effect the system. Well, the cable changes don't effect the system anywhere near the level that the loudspeakers, the amplification, the pre-am, and the source. And my room makes a big difference in what type of sound I can achieve. Well, I am getting off the track which is why I don't typically write reviews but lets talk about how the Pass XA60.5 Monoblocks effected my system. In two words, MAJOR CHANGE. The Woodmeres are being driven in a totally different way. The sound is effected whether I am playing the system at low, mid, or high volumes. My sound with the Pass XA60.5 Monos has all of the great qualities that the 30.5 stereo amp offers and much more in addition. Here is what I get. I get a much fuller, richer sound (much more weight to the sound). I get an even greater realism to the performances of the artists. The dynamics to the sound is dramatically different . The pacing seems different and the system is delivering a much bigger sound. Bigger is not just louder but more importantly, is that sense of involvement and engagement with the music whether it is the highs, the midrange, or the fantastic bass response. In my system in my room, the monoblocks just electrify me so much more than the stereo amp. The bass response is much tighter as the drivers are being controlled in a much different way. Having separate power supplies to each speaker makes a big difference in my system. I spent a tremendous number of hours listening this weekend and keep coming back to how wonderful the music sounds. By the way, having a terrific dealer like Mark at Reno HiFi makes a big difference as I was able to try the Pass XA60.5 Monoblocks and compare them to my Pass XA30.5 Stereo Amp and either buy the monoblocks or send them back to Mark and keep my stereo amp. Mark, unlike many dealers I have worked with in the past, is willing to have as many conversations about the products all through the various steps of a purchase and is someone who is honest and very easy to work with. You never feel guilty calling and having as many conversations as you want about a product. Thats just the way it is with Mark.
Conclusion:
I think the Pass XA60.5 Monoblock Amplifiers are terrific and are probably the best solid state amps I have owned. They have so many outsstanding qualities but on a simple level, they deliver the music in a very engaging way that makes you want to get out of your seat. The amps present the music in a very natural way that both includes a seductive midrange combined with excellent dynamics. I can listen for hours.
Sorry, if I rambled to much but speculating how a particular component is going to sound in anyones system is very hard to do and it is best to try try to hear a product before you make a judgement to purchase it. Audiogon thoughts and opinions are wonderful and we are lucky to have such a great forum to express our thoughts but in the end, your ears will determine how something works or does not work in your system. It is a trial and error and certain components work better with other components than others and all components are most effected by the room in the end and that is our biggest challenge, to get the most out of the room. By the way, I am certainly no expert , just another person who enjoys music and keeps listening. These are just my thoughts and I respect other opinions as long as we treat each other with respect and allow disagreement in a constructive way. Stephen
