New BHK 600?

I wish there was someone I know who had a pair of BHK 600’s so I could go listen to them. Someone with FR30’s. Someone who was available over Labor Day weekend.

I think you might know such a person.

I just hope he’s available. I should stop along the way and have a beer with you!

Would be a hell of a detour to South Carolina.

@straightwire i think he’s hinting he may be in the area Labor Day weekend. Lol

I get the not-so subliminal message. I will check with the person who checks our schedule. I am open to it if I am available. They are supposed to arrive today. I am putting black socks and tennis shoes on for the total out of the box experience.

Al’s gonna need a bigger boat–I meant house.

The BHK 600 Product page is now online.

I watched Darren‘s nice video.

Just to understand the following sentence of the product page which Darren didn’t refer to:
„It is the only fully linear power amplifier of this size that is fully balanced from input to output.“

What’s the special case here?

That there’s no other fully balanced amp with that power handling?
That there’s no other linear (what does it mean?) power amp with fully balanced design and/or that power handling?

I’d like to understand where’s the usual limit and the special challenge of the combination of those 3 characteristics and why. Is it more difficult to make a fully balanced design with a high than a lower power rating? Or easier to make a linear design if not fully balanced etc.?

Tech people might directly understand, but as it’s on the consumer orientated product page, I try to get it.

Anxious to watch another video then during your unboxing and set up. Congrats, I envy you a lot!

Interesting power statistics. Rated 600W at 8 ohm. 1000W at 4 ohm. Stable for transients at 2 ohm. No spec for 1 ohm.

I bet it was an interesting internal debate as to whether to spec at 500W or 600W at 8 ohm. At 500W, you get the coveted “doubling” to 4 ohm (even if not able to spec a number at 2 ohm). At 600W you get the nice double in power from the existing BHK 300’s, which is nice for marketing I’m sure.

I guess not surprising that they chose 600W to spec at of those two choices, but not a trivial debate I’m sure.

I don’t think any amplifier can truly double it’s power when impedance is halved, most manufacturers underrate the 8ohm measurement. I would also think that distortion would have to go up at least a little with each halving of impedance.

Sure, it’s always a choice. And almost everyone picks round numbers. Except Rega - they spec’d one amp at 105W and one at 78W if I recall.

Is amplifier power output calculated based on measurables (current, voltage, resistance) as opposed to measured which leaves some room for interpretation?

I noticed the 250/300 specs indicate double the output at half the impedance

I can’t answer your question, specifically; but my observation is manufacturers tend to pair their power ratings with the best possible measure of the distortion type of their choice they can achieve.

FWIW.

I must admit that claim (“The BHK Signature 600 Mono Amplifier is unique in all the world. It is the only fully linear power amplifier of this size that is fully balanced from input to output”) seemed a bit dubious, given I was looking this morning at my dealer’s offering, the Soulution 701, also 600W into 8 ohms, etc. fully balanced and some other heavy duty figures:

  • More than 1,000,000 µFarad storage capacity in the power supply unit (BHK600 says 300,000uF )
  • Peak current rating of more than 120 Ampere (BHK600 says ?)
  • Peak Impulse power rating > 12,000 Watt (BHK600 says 2,000w)

OK, the 701 is more expensive, but I wouldn’t want to be in the room when peak transients blast away at 12,000w.

In case it betters the BHK in 1, is the same in another of those 3 figures, maybe the Solution is not fully linear, whatever that means?

I assumed all power amplifiers aimed to be linear. It’s sort of a basic requirment.

Maybe all amplifiers are linear, but some amplifiers are more linear than others.

Gee I hope my 250 is fully linear, otherwise I might have to stop enjoying it.
