Simaudio is aware of this issue and are working on it. I have spoken with them and was assured I will be contacted as soon as they have a solution. I will post when I know more.  

  You can definitely leave JRiver playing and turn the volume off and it will still burn in. I just left my 230HAD playing Radioparadise at very low volume non stop for the first few weeks when I wasn't around to listen.   I don't know if leaving anything plugged in with the volume off will...

Another review of the 230HAD in the October issue of Tone Magazine. On page 127 the reviewer has some nice things to say about the 230HAD.

There is a nice review of the Simaudio 230HAD in the latest Hi-FiNews & Record Review (November issue) Magazine if anyone is interested.   They seem to like it a lot and I would agree with their assessment.

I very much agree. The performance of the 230HAD gets pretty close to some of the best out there at a much more reasonable price. The rule of diminishing returns certainly applies here.   I also think, as I've read in this thread I believe, that the 430HAD as opposed to the 430HA brings a...

I think you are correct that it does not seem to be a hardware issue with the 230HAD. It seems to be a Windows 10 USB thing.   My 230HAD only makes a very faint random ticking sound - no pops or crackles here - when accessing internet radio sites. Never from locally stored files. Also, my...

  I know my wallet wishes I'd never heard a difference.   Agreed. It's all about the music.   Cheers.

It's all good. Different horses and all that.   I am curious what cabling you are using with your 430HA? I have a preference for a warmer sound. More a fan of Cardas than Nordost, if you know what I mean? In any case, I've been really liking some of the newer Audioquest cables with the...

No worries.   The 230HAD is what led me to purchase the 430HAD. They both have the same house sound, if you will. Smooth, detailed, a bit warm and a very quiet background. The 430HAD is that much better at ease of presentation, space, flow and a greater degree of dimensionality.   Whatever...

TonyNewman, I have both the 430HAD and 230HAD. I don't think the 230HAD will give you what you want. I find the 230 and 430 more alike than dissimilar. Just my opinion of course.

  Thanks for posting this.   I too am deciding on the next purchase from Simaudio to go with my 430HAD, 230HAD, 260T and 280D pieces. Not as straight forward as it seems.   I have listened to both the 340i and the 350P with a 330A but only in a system context and without listening to the...

The 230HAD took about 300 hours to fully settle in. Don't get me wrong - it is very nice out of the box but it simply becomes a better, more balanced amp with some time on the clock. Simaudio gear really does need some burn in time to get the best performance. Bass is now more balanced and the...

I look forward to your impressions.   aptX streaming on the 280D is quite good actually. No drop outs or stutters and the sound quality is more than adequate for background music from various internet radio stations at higher bit rates. I compared it to aptX on my Audioengine B1 and the DAC...

I think you are going to really like the 380 DSD. It has the same level of upgraded power supply as the 430HA. I wish I could swing it myself but the 280D is pretty good in it's own right and financially will have to do for now plus, I do like that I can use APTX from my tablet which can't be...

Agreed, I expect the 430 and 230 DAC sections are quite similar but the surrounding circuitry and power supply improvements really should make a marked improvement for the 430. The Simaudio Evolution series volume control should also bring something special to the 430. I very much look forward...

I have had my 230HAD for about 3 weeks and have let it run non stop. The 230HAD really comes together in week 3. From your description the fullness that it is capable of really happens around the 300 hour mark. The top end also smoothes out and there is more flesh on the bone so to speak.   I...

Thanks longbowbbs.   I was thinking of keeping the 230 for just the PC side and moving the 430 to the main 2 channel system and using it as a preamp with my 260T and 280D and a 330A for a full Simaudio system. Alternatively, I could sell the 230 and just use the 430 in the headphone/PC system...

Have you received your review 230HAD yet?   I've had mine for about 2 weeks now and would like to hear your impressions in comparison to the 430HAD which I have just ordered. It should be here next week. Just wondering if it makes sense to keep both pieces?

I will have some further impressions in a day or so. In typical Simaudio fashion the 230HAD seems to take a few hundred hours to settle in particularly on the headphone side. The DAC has been running 12 hours a day for the last week and a bit so I'm getting close to taking a critical listen.  ...

Just received my Simaudio Moon 230HAD today. I will also have a chance to compare it to the Simaudio 430HAD in the next week or so. I will let the 230HAD burn in overnight and have a more critical listen with a few more hours on the clock.   Straight out of the box, as a DAC, it sounds very...

Thank you for your review of the 430HA. I currently have the same DAC in my 280D stand alone unit and pair it with a 260T transport. Just about to order a new 340i for the two channel rig too.   I have heard rumours of a new headphone amp on the way later this year from Simaudio so have been...

I wouldn't characterize the sound as lacking in extension. All of the top end detail is there - just not a particularly open, airy, in-your-face, hi-fi sort of presentation out of the box if you know what I mean? A different presentation to be sure. To me, it seems a very natural, easy to listen...

Already getting hints of that. Had a listen early this morning and some of the midrange sounds actually had me thinking they were in the room with me! Dynamics in the mids seem to come on board first along with a more linear top end.   I noticed you have the Simaudio 430HA. I too am a Simaudio...

I agree. I've had my NightHawks playing away for the last 12 hours or so and have already noticed some changes - all for the better.

I received my pair of AudioQuest NightHawks this afternoon. One of three pair that made it to my local Audioquest dealer. Managed to have a quick listen out of the box and then let them run for a few hours.   First impressions on the product and packaging is very high. These look the part with...
