I'm considering getting Klipish Heresy IV, anyone know if the Cayin HA-300 will be more than enough for them ?

The sensitivity on Klipsch speakers seems to be calculated in a unique manner but in reality is about 3db overstated compared to most manufacturers. So if we say that's 99-3 , you should have a real world 96. The impedance curve is supposed to be reasonable so it comes to the size of your room and how loud you listen to your music. If you have a medium size room of about 1200 cubic feet or less as long as you don't listen at crazy levels then I'd say you should be ok.
My speakers are 96db and with a flattish impedance curve and need between 11 o'clock and 1 o'clock on the volume dial to give sufficient listening volume.
Of course I'm sure any decent dealer should let you try before you buy?

G'day. New HA300 owner here from "down under". Bought mine from Jaben Singapore. Shipped direct from China to home. I notice it is a 220 volt model. So I've had to go and get a mains regulator that puts out a constant 220 volts from the wall mains which is 240 ish volts. As you can see from the attached photo, more often than not, the mains is frequently 246 volts +. Now that is outside the 220v tolerance, is it not? (I have a PrimaLuna pre-amp, bought locally. That has "240v" stickers on the amp and on the box. Made in the Cayin factory, so I am reliably informed.)

A basic question: when do people start listening to music after powering on this tube amp? I'm used to the PL where there the system is 'mute' for 30 seconds while the system warms up and then a green LED comes on. Thanks.

The general voltage tolerance is +/- 10% rating, so in this case, one rated for 220V should work fine at either 200V or 240V. I'm not sure what the situation is with feeding it a constant 246V like what you showed, but as a personal person, I'd skip the step-down transformer and run it direct in that case. I don't know whether the internals are actually different for 220V, 230V, and 240V countries, but I have my suspicions that there aren't any in a mass market product. As a personal person, not as an advisor.
In my case, I'm running a 220V version at 219-231V, in a 220V country. All without any issue.

I have always warmed up my tube gear for >30mins before listening, and that it was I do now too. That is also what led me to following solidstate for a while, it's much more convenient about the power-up and power-down cycles.
Thanks for your experiences Benny-x. I did plug the HA300 straight into the AC mains outlet (that's supposed to be 240v) before delivery of AC mains regulator. Worked and sounded fine. However, it was obvious the Power Supply Transformer was much hotter (hot to touch after a good listening session) running from the wall socket c/w running from 220v from the regulator (just very warm).

can anyone compare this amp to the little brother Ha-6A?
Which differences in sound signature do they have?

According the comments section in , this reviewer is supposed to be doing a HA-6A <-> HA300 comparison soon.

For amplifier wearing 220V label, our QA process will test the amplifier with 230V +/- 5% before the amplifier leave the production line, so 218V to 242V are consider normal power supply to the amplifier, and 207V to 253V are still acceptable. I won't worry about 246V, it certainly will run warmer than feeding with regulated 220V, that's natural even when we purposively design an amplifier for 240V +/- 5%.
By the way, you live in Australia and buy your HA300 from Jaben Singapore? That's kind of weird.

@project86 had published a very detail HA300 review and he is working on HA-6A review right now, with a bit of luck, we should be able to read his review on Darko very soon.

It is here.......well kind of.......good review though

Can I / Should I connect 4 ohm speakers to the HA-300? I've read in the forum the speaker outlets on the HA-300 are 8 ohm. Hopefully, by the end of this year, I will get my hands on some Tekton super-sensitive 96 db speakers. (Very, very, very, very long lead time to order many Tekton models.) They are really meant for my main system. which has a pair of solid state mono power amps. Hence the 4 ohm Tektons have been ordered .
Price was cheaper from Singapore. Australia seems to have the Distributor-Dealer hierarchy, each adding their own margin to the price.
