Solid State Low powered Amplifiers

While it may appear logical to pair a speaker of high sensitivity like the Cornwall IV with lower-power amplifiers, experience suggests that more power can result in better performance. See the following review (but not limited to).

With technological advancements, a well-designed and constructed Class A amplifier does not generate as much heat as it used to. The Accuphase A75, if you can afford it (or are willing to), is a good example. I spent a good hour auditioning it in a store, and to my surprise, it does not feel hot. Feedback from its users echoes the same sentiment.

While rated 150 wpc (8 ohms; 225 wpc 4/2 ohms), 35 amp high current pc, my class A/B Parasound NC 2125 v2 generates much less heat when switching to 2-4 ohm stable operation load tap, as compared to another class A/B A23 and it sounds better to my ears. Specs like SNR is better than some aforementioned gears.

Heat is less of an issue and concern nowadays if you delve into the subject further. Don’t settle for the fantasy of using a low-powered amp for less performance with a $6-7k speaker.

One benefit bestowed on the systems’ sound with the ModWright’s 225 Watts was, you guessed it, more control throughout the frequency range. With the ModWright driving the Klipsch, the overall presentation was more balanced, more put together compared to either of the tube amp partners while tone and texture felt very nearly as full as it did with the Feliks 300B. What’s more, the system’s ability to reproduce subtlety also improved along with greater dynamic slam. A win, win, win in my book.

@moose89 from your OP it’s unclear if you want a SS integrated, or just a power stage.

I used KT 66- and 88-based integrated’s for some years until I fatigued of the amount of waste heat and tube lifespan (+ listening windows) lost to warmup time.

I am still using the older SS integrated I picked up due to its similarity (to me) in sound to the tube amps, and with pretty high efficiency speakers (~99 dB if not calculated slightly lower for a minor discrepancy in frequencies > 6 kHz).

So, integrated, or power amp being what you prefer here?

The Schiit Aegir 2 should be released before the end of the month. It sounds like they are playing with very low feedback. The Output Impedance is .8ohm… Damping Factor of 10. It’s 25w/ channel into 8 ohms.

With that low Output Impedance, I expect it to be very musical and plan to buy one.  Price with tax & shipping probably puts it right at $1000… maybe a few bucks less. I have a hunch it’s going to be a special unit for not a lot of money. 

I am in exact same situation.  Class D is now competitive in many areas with Class A/B AND Class A.

Listen to the low end FOSI V3 and a high end purifi amp.  I think you will be stunned how good they sound.

You want the Class D amps with the new feedback topology that eliminates the rise in distortion at higher frequencies.  

that schitt unit has the advantage of allowing bridged mono use, thus in the future, there, or somewhere else, you can get another unit to drive ____ speakers
