Plinius SA100MK3: VERY AMAZING AMP. This amp has a gorgeous amount of detail and nice bass. i was very impressed by how much bass it retained even a low volumes which is a hard thing for many amps to do! I really don’t remember ANYTHING bad about this amp. It sounded very nice with my Dynaudio C4s.
Plinius SA103: I bought this amp because i thought the SA100MK3 was amazing so i had to try it. Anyhow, i found this amp very detailed, great overall tonal balance, BUT I DID NOT GET THE SAME OOMPH in the bass department that the sa100mk3 had. I called plinius several times and they told me this amp uses dual transformers and that i needed to re-wire my electrical outlet with a 12 gauge cable, etc, etc which i was not going to do. I felt this amp was a tad more detailed than the plinius sa100mk3, but if i am being honest here, i preferred the sa100mk3. It had bass that "thumped" at any volume level.
Octave Audio v110 integrated: i tried this unit with my Confidence C4s and i will say it REALLY impressed me when i first turned it on. I mean, it was like my speakers became something else. TONS OF BASS that i couldn’t believe what i was hearing. I liked it so much that i wanted to keep it and made it part of my home theater by using its passthrough mode. That said, it just didn’t really keep up with the rest of my amps. It got lost time and time again when action scenes came on. It almost felt as if my front speakers were not even playing at times. I later just realized that Tube amps just don’t have the dynamics and slam needed for movies. I must have tried all sorts of settings, calibrations, etc and i just couldn’t get it to blend with the rest of my set up. If i had a channel set up and no home theater, i would have certainly kept it.
ATI SIGNATURE 4007: Here i was again. Trying to see if maybe i didnt give the 6007 signature amp a fair shot when i first bought it so tried this less powered version. I found that it really is a solid amp if you are looking to do 100% home theater with occasional 2ch listening. This is the amp that you throw in a rack and shut the door and let it play for years and years and years without ever worrying about it. However, it is NOT IN THE SAME LEAGUE as the JC1’s, pass labs, Krell 402e, etc.
EMOTIVA SA250: I was actually very impressed by this affordable amp. i connected my crazy expensive mcintosh c1100 to this amp and i really was amazed by how it handled my electrostatics. I could say that there were other amps that were far more expensive and yet they couldn’t hold a candle to this amp. It had plenty of everything and i really thought if this amp was made by someone else, they could charge 10 times more for it.
Someone above asked me why i don’t try tubes and i think i pretty much said why above. I just feel tubes are awesome for 2 channel and i probably would have an all tube set up if all i did was 2 channel, but in my situation i need an amp that can excel at both.
As far as the xa30.8, that is one great amp. I think it is the amp you use if you live in a nice studio apartment with a nice pair of focal diablo bookshelves speakers or Dynaudio C1s (or something like those) and you do serious listening late at night without ripping your neighbors walls off. This amp will give you every ounce of detail and 3 dimensionality that you wish to have, but IT IS NOT a monster and dynamic amp as the 350.5 or 250.5. or 250.8. The xa30.8 is a very intimate sounding amp. It is not the amp that will make your jaw drop when you let it blast as loud as you can handle. That is when you purchase the x250 or x350.
i want to be very honest, and i want to put this out there. i find the XA pass labs amps to be amazing amps, but you WILL BENEFIT from having speakers with powered woofers such as martin logan electrostatics, goldenear triton 1s,etc. In my personal opinion, the best amps to come from pass labs are the CLASS A/B amps. Any X series amp to be specific. They just have outstanding slam and will knock you back in your chair when you crank them up. Up until this day, i still have not heard a better slam and dynamics than the pass labs x series whether it be the .5 or .8.
One last thing i wanted to say is that i am writing this out for all of you who are looking to gather as much info as possible in order to make a smart buying decision. However, my reviews here are based on my own experience and not what some reviewer got paid to say on a magazine. i don’t get paid, i don’t make anything from this. It is just my passion/hobby. Some of you will recommend other amps from brands that nobody has ever heard of or that are so unknown that i simply won’t dare to buy. Why? because as you can see i go through amps almost on a weekly basis and i also need to be able to sell them when i want to try the next amp. Does this mean that i am missing out on a lot of other amps? i am sure i am, but i am also being smart about my buying decisions. Essentially the sale of each amp finances my next amp purchase. i can’t buy an amplifier that i simply can’t sell for 3, 4, 6 months etc.
One more thing i was thinking about doing was to give my opinion on processors. I have owned quite a few as well and can certainly give my personal opinion on many of these, but that will come later.
Anytime you see something that i am selling, rest assured it is only because i am looking to move on to the next thing and not because there is something wrong with it. I could be totally in love with an amp today and think it is the best I’ve owned, but i will still move on from it when something else catches my attention.
In the meantime, i will continue listening to these 601s.
cheers!
