Solid State Low powered Amplifiers

@Riccitone I have the FleaWatt Coltrane on the way from HI…thank you for that suggestion . It sounds really great and low power is what Klipsch enthusiasts all recommend in the reduced field listening that I do….and for the remaining Winter, the SMSL VMV A1, for experience reasons,I will welcome on Saturday. The Cornwall iv for me is just so airy that I hate jumping up too far up in WPC. Like most audioholics, I’m stockpiling and will make decisions on which to send to market, rather than sit on a bunch of amps. I cannot imagine I’d sell my Dennis Had Inspire SET 300B… and it’s just as good without WE300B, with Full Music solid not mesh, and Genelex Gold Lion…to my ears. And after waiting on Hegel 120 to appeal to me, it’s just made for a larger scaled listening area, as I cannot supply the increased volume to predicate enough gain to appreciate the beautiful bass and power it wants to unleash on the efficiency Klipsch Cornwall IV’s possess.

To @moose89 Thanks for sharing your experience about the type and amounts of power you enjoy and recommend using with the Cornwall IV speakers. 👍

This topic and how you explain the differences between your DH 300B amp,-vs- the Hegel 120, relative to the type of scale and listening area space is very interesting me. It’s becoming even more clear how finding the right amplifier(s) for Cornwall IVs (and other efficient horns) can make a real difference in the outcome and listening enjoyment. Or, this one study path I’m keen to learn more about, after helping a local tech friend do the early design on three pairs of Altec Onkens. He now uses heavily customized 8-watt Audio Note monos with original WE300B tubes with them. I heard that setup twice, and it was quite different from anything else I’ve listened to, to date, since. It also showed me what big horns can do.  

I’ve followed along (and owned a few amps, listened to) from Dennis Had-Inspire and Nelson Pass/Firstwatt over the past few decades, and the more recent paths both have followed into "lower powered amplifiers" for tube and solid state amplification.

I hope folks here can share more about the NEW Cornwall IV scope of discussion for recommendations on what amps work best with them. This would be super helpful. While I cannot own them, I have a few buddies who consider them and back off. One friend is adamant, now has me convinced the II, IIIs, are notably different in design than the new IVs, and the correct amp paring truly matters. I have yet to hear or enjoy Cornwall IVs with proper amplification, and hope to.

Geez. Like holographic soundstage demential sound? I just found my answer to balanced sound, thanks to @riccitone. I went right to it and purchased this amp that he suggested that I have never heard of and I’m sitting here in amazement.I know we keep searching and I don’t think I have to anymore because this sounds too good to be true even better than the Cary KT 88 sound and the 300 B sound from Dennis Had. PERFECT marriage to reduced field and Klipsch, with enough head room to the friends that come over and you really want them to enjoy the listening experience, but they have to say “turn it up””…. Scary loud and with my Bluesound node X as my preamp and volume control. It is in need of nothing else because I am not a phono LP guy anymore. FLEA AUDIO Coltrane!

I’ve also used First Watt J2, Nakamichi PA7, Marantz 2226B, and this is my new best friend. The others were big bullies. 

I have a Valvet E3, a First-Watt F8 and SIT-2 and all of them are class-A and are terrific sounding.  The F8 has the most power over the other two however for fairly efficient speakers, all do very well.  Each have their own sonic signature and I have had the pleasure of listening to all of them taking turns with them each 1 week at a time.  My favorite of the three is the SIT-2 although between the three, it's a matter of splitting hairs on which sounds the absolute best.  I believe for the Cornwall speakers at 98db, any of the 3 would be great.  They are all reliable especially the First-Watt ones.  I've used these on my Living-Voice 93db efficient speakers and any will drive those speakers to uncomfortable listening levels with no sign of compression.  You can find the Valvet E3, and occasionally an F8 on AudioMart, however I haven't seen a SIT-2 for sale yet.  Highly recommended !  

I use a Keces E40. $750 with a preout, two RCA inputs, a mm phono stage and a usb input with internal dac. I think its suitable as a main driver, desktop, or spare in case one is in-between or having their amp repaired/serviced.

I think its a better option than most of the others near its price point as well as those higher priced. That includes the small Regas, Spark and Emotiva if not for outright power output but for SQ and versatility. Small form factor and 10 lbs. Comes with a remote.

I have two and they drive my smaller speakers well ranging from 4 ohms to 6 ohms, but those that dip well below 4 ohms over a larger frequency range will heat it up (Dali Menuet SE), otherwise heat is not an issue.

Distortion on a Klipsch speaker rated at 102 dB at 1 watt may or may not be low enough for you but it won’t sound sterile, IMO. At 8 ohms, 0.2 watts was measured having 0.3%THD+N, decreasing as you increase power but can be modulated by using a pre or dac with a decent pre. At higher output, say 2 watts, distortion falls below 0.08%.

Its pre section was stated to have a class A sound and its smooth and very close to my Hegel on my speakers at the SPLs I listen at. If you listen primarily to the Hegel, you may notice a very slight difference between the two but not for long as you adjust. Bass is better on my smaller speakers for two reasons, one the high damping on the Hegel can be too much and the Keces adds from 1 to 2 dB from around 50hz to 30hz, which adds a bit more of support but still sounds relatively fast, tight and layered.

Can’t say how it will sound on the big woofers but I like it. I think it outperforms alot of the above mentioned budget options due to its superior SNR, dynamics and damping in comparison.

Per one review, here are how it spec’ed out:
