Pass labs xa30.8: very musical/smooth. Has good bass output,but it is not the amp that you crank up really loud. It is perfect for those of you who do a lot of moderate to low volume listening sessions. RUNS HOT AS HELL. My lower legs were sweating after a 2 hr listening session.
Classe 5200/2200: Very musical. OUTSTANDING midrange and no ear fatigue of any kind. Has good bass, but it is not its strength. Its strength lies in the smooth highs and great midrange.
Classe 5300/2300: more transparent than the 5200, but i think it is a cold/boring amp. Nothing really stands out. It lacks the 5200's musicality/sweetness.
Classe CTM600's monoblocks: Massive power. they got louder than the 402e, but lacked the 402e's bass control. Also a very cold/neutral amp.
Krell 402e: The best stereo amp i have owned period. Massive bass control at any volume level. Amazing smooth, liquid highs that sparkle without any fatigue. Runs HOT AS HELL and my electric bill went up about $70 dollars a month.
Krell Chorus: Good bass control. VERY DETAILED, but can sound somewhat "piercing" to the ears at high volume if you have the wrong speakers. i actually brought over my buddy's dynadio c1 speakers and i DID NOT like them with the chorus. Nice detail, but once you put the pedal to the metal, it might sound too forward for some of you UNLESS you have ribbon tweeters. My goldenear triton 1s don't seem to mind the chorus at all. However, those of you with Revels ( i also own the salon 2's) or any type of dome tweeter will need to look elsewhere because the highs are just too much.
Theta Digital Dreadnaught D: i have owned it for about 3 days so it is still being broken in. So far, i can say it has MORE DETAIL than the Chorus. It has made me hear the slightest details that NO OTHER AMP has allowed me to hear (this includes the 402e).
This amp sounds OUTSTANDING at any volume level. It does not scream when cranked up, but rather just gives you more volume. This amp lies somewhere between the krell and Mcintosh as far as high frequencies meaning it is not forward nor as laid back as mcintosh.
I like the krell chorus when first turned on. Nice detail and bass control, but after about 90 minutes of listening to the chorus at about 90 db, my ears have ear fatigue which makes me want to stand up and go run errands.
Throughout the past 2 years i have realized that amplifiers (high end amps) are no different than tv's as far as grabbing your attention. Think of it like this, when you go to your local best buy shopping for a tv, we typically go "wow" look at how awesome this tv looks and it is probably the tv with the brightest, craziest settings. This is done to grab your attention temporarily, but if you had that tv in your living room and watched it for one hour, your eyes would hurt. This is why you typically see the THX SETTINGS on most displays being very dull/dark/dim looking, but these are the perfect calculated settings.
Amps are the SAME THING. Some sound amazing in the first hour and then after a few hours, you want to turn the volume down. The theta does not do that. It sounds somewhat laid back when first cranked up and then as you sit there for a while, you realize that all the detail IS THERE!.
I will elaborate more later this week on this amplifier.
