Why it it higher than the other review I saw?

SNR of A90
Using the same condition as the other review, it should be 136dB. Idk why it's lower on his. 141dB is tested with unbalanced in.Why it it higher than the other review I saw?
If you don't put lol in the end....Can someone please explain the power specs to me cause in the review it says its 3 times more powerful than the thx789 but when i look at the specs i dont see it. The 789 is 6w and it looks like the hpa4 is as well? What am i missing lol
Firstly, no.Is channel frequency not being 1.00000 hz exactly a problem?
YesDoes anyone know how they managed such a low crosstalk number?
John, That's mean LOL
OK, here is the long answer:John, That's mean LOL
It's always good to start one's audiofool day off with a chuckle. As long as your not drinking coffee at the time.John, That's mean LOL
Does anyone know how they managed such a low crosstalk number? Absolutely inaudible but very impressive nonetheless, it's a good 13dB lower than the ADI-2 DAC
I am using a Pronto remote. The LA4 mute, volume up/down, and input up/down are the codes used for the DAC3. Try using that device. As I have mentioned before, the direct input commands do not work unless used with a companion DAC2/DAC3. Benchmark,, Benchmark, Bueller...
So it looks like Harmony has the DAC2 HGC in the database, so the IR codes are there.
The bigger issue is that Logitech tags devices for inputs a particular way in their device database, for the automation side of things. Fortunately, it is possible to tell Harmony how the inputs of a device are handled. Unfortunately, it's not well documented on how you make the configuration button appear for a device so you can do that. I'd probably have to reach out to Logitech support to figure out what the secret sauce is.
I know your post is a bit old, but the LA4 is a preamp I'm looking at, and I use a Harmony, so I had the same question. I did a bit more digging and just wanted to share with others what my findings are.
Ooh! I had the dynamic driver version of the Jecklin Float in the late 80s/90s. Very comfy but not much bass. All the foam padding eventually degraded.At least Stax came with their own amp. Still expensive. You could buy them individually. At the upper end Stax offered the SRA12S which included a fairly full function preamplifier--the HPA4 of its day. $500.00 ($2100.00 in today's dinero--phones extra).

Then there was the Jecklin Float (imported by Mark Levinson). At three hundred dollars ($1500.00 in today's funny money) it gave you that authentic Zombies of the Stratosphere sci-fi experience (girl an option at extra cost).

I had the remote and used the Pronto remote to learn them. The direct input do not work without the DAC 2/3 connected. I'd hoped that Benchmark support direct input by now.

So how does one integrate this unit (or the LA4) with/without the rest of the Benchmark lineup (amp and DAC), into a 2.1 or 2.2 setup WITH room correction/DSP? What are the options here? The HPA4/LA4 is very impressive and gives a lot of nice functionality, but it doesn't provide any accommodation for bass management other than some parallel outputs. It would be great if the volume could control 3 or 4 independent channels instead of just 2.
Alternately, one could do all the DSP (minus crossovers) in the digital domain upstream of the HPA4/LA4, but then how do you handle input from multiple digital sources, never mind analog, and have DSP apply to all? I'd love to see a DAC with digital effects loop I/O, post input selection and pre DA converter.
Mr.Siau works for Benchmark. And inserting a Benchmark between DAC3/AHB2 improves the sound clearly. I use this three units combo for 2 years. It's very very transparent.This is astonishing. Never heard of a preamp actually improving your system. I might have to buy one of these.
Wait. Do you work for Benchmark? I feel like that should be disclosed.
