Are they worth it - meaning - Are they a good buy, sound quality for the cost?
This totally depends on what specific improvements you’re looking for and what sound characteristics are most important to you. What amp are you using now, what’s your budget, and are you looking for new or used? No amp is a good buy if it doesn’t deliver the sound/improvements you’re looking for.
Good qualifier to the question. To answer:
I originally had a GFA1*, which as it aged, hit that point that the sound quality went sideways. I replaced it with a PS Audio Two C, which is a good sounding amp, however it does not have enough power and find it lacking, when pushed at high volume levels or with significant base. I listen to rock/easy listening, classical and Gregorian chants - so somewhat varied.
By good sounding to me: meaning it does not color the music and allows details and transparency to show at reasonable to louder sound levels.
So, need more power that will drive a somewhat efficient speaker (90db).
Also, the current price point of most better sounding equipment is outside of my budget. The Khartago+ is a stretch, from a budget perspective, but the feedback I have seen indicates it is at a good price for the performance it delivers. It also has a good step up in output - wattage/current.
*before anybody diminishes the GFA-1, this one appears to have been something of a unicorn, as compared to the GFA-1A, which I also own, the GFA-1 sounds open, allows details to show and is much more transparent than any other GFA-1/GFA-1A I have listened to.
I"m happy with mine. I have a pair of monos and a Candela pre amp running a variety of larger speakers in my second system and have a stereo Odyssey running a pair of 805D4 in my living room, they all sound and work great.
Absolutely! My Khartagos drive a pair of Aerials which require huge current for power and control. They replaced an Aragon 4004 MkII, another great amp, but it had intermittency issues with one of its channels (and was used in a much larger room).
