Buckeye Amps: New US based Hypex multichannel amplifier builder, line-up announcement!

[Golfx]

I was just worried about the input sensitivity from my Denon X3700H — read that there may be issues outputting beyond 1.4V, and the 502 amp needs 2+V for max output.

You can just call Dylan (Buckeye amps) for his recommendation to set your concerns to rest.

 

[Bimbleton]

Yeah, I think I’ll defer to what Dylan recommends. Thanks!

I have an older Marantz and have never heard of these AVRs being limited to that 1.4v number. It should not be a concern!

There are no issues using the Denon 3700/4700 with the NC502MP. The 1.4V mentioned in the ASR review was simply the best SINAD reading. The Denon receivers can offer well past 2V but you will go deaf if you leave the AVR at those power levels with the Revel 226BE. The Revel F226Be sensitivity is 88.0dB for 2.83v at 1 meter with the C426Be at 90.8dB for 2.83v at 1 meter. You will have more sound power than you need even at 1.4V with the NC502MP.

As a comparison, my normal listing level of 80dB with my Revel F328BE only requires a few watts from the Buckeye NC502MP. It's easy to worry about nothing in this hobby.

How do your Revels sound with the 502? Pleased with the sound quality?

The Revels sound great with the NC502MP or the Purifi amp. It's really hard to tell a difference between the two in my A/B tests. The only difference I can easily see is the NC502MP case will be warm after an hour of music while the Purifi amp case stays amazingly cool.

My Revel Concerta F12's sound very good with my NC502MP, even driven to ear-splitting levels (110 dB SPL on drum hits). But then they also sound superb on the prior B&K amps. The B&K amps just didn't have as much power.

I didn't compare them side-by-side, but I recently helped set up a friend's multichannel system. It uses a Marantz 8015 AVR, F228be fronts, C426, M-whatever surround and rears, and a couple of Revel subs (7.2 set up). After calibrating it, it was very good in stereo mode listening to music, but it noticeably didn't get as loud as my system. I think the 502 has easily twice the power of the 8015, but with less headroom (whatever that means). (I mention this simply because Marantz and Denon are so closely related.)

Trying to decide between a change to a new binding post (wouldn’t be until next year, if I go that route).

Which one of the two strikes a fancy?
(Both are robust, mount the same, perform the same)

 

[Matias]

AFAIK the plastic cover is safer to avoid a conductor shorting 2 posts.

 

[thegeton]

The one on the left looks more user friendly - larger knurled surface area for stubby older fingers. The one on the right looks fancier, similar to other fancy amps. I would go with the left if it were up to me.

I like the one on the right

 

[Golfx]

The one on the right appeals to my eye. The one on the left appeals to my boring logic.

Go the black, Dylan

I would love to see the ETI Research BP-20C binding posts available on Buckeye amps. I have them on my other Purifi amp and they look amazing and work great.

Not at that cost per pair.....

 

[droid2000]

Right.

 

[amper42]

$30 a pair for a quality binding post seems reasonable. If not, I certainly would pay the difference if an option was available. When you pay $1000 for an amp quality binding posts for $30 a pair is something I would opt for.

There's a lot of hyperbole in ETI's marketing...

Steel binding post tabs/washers on pre-2023 Buckeye amps weren't a problem either until testing proved otherwise.

Agree and may be even beyond that…

Was I the only one left wondering if their top of the line Kryo was Cryo(genically) treated?
