That's a very good question, I own a 400EX and also curious. Looking on their download page, I'm only seeing those two updates. I'll have to look what firmware I currently have on mine but I think the latest issue might be 1.01? I will say it does sound very good, very much a AKM sound and in...

These are great amps, total bargain. I used mine today with my Stax Lambda's and love the sound. I've also have a Stax 8000T and LTA Z10e and the Stax SRM-1's are really good for the price and easy to work on if ever needed. GLWTS!

PitSteelers69 was great to deal with, a very nice person, quick communication, a knowledgeable audiophile with experience buying & selling audio gear. Item quickly arrived, Well described, Well packed. Gladly recommend PitSteelers69. Cheers

Since you've now had more time with the two of them? I'm very interested in hearing more from you the comparison between the two. I had used the Aqua LinQ extensively in the last two years in my system but now very interested in the Rose 130 and in it's sound quality (the good & the bad) when...

Any opinions on the new AKM DAC inside the Pro Plus version? Are you liking the sound and has anyone compared it to a good outboard DAC? Like a Denefrips or SMSL?

I would say go for the D400 Pro, it will (supposedly) give you a AKM sound similar to the EX without having to spend more money and if you love the sound, then you can step up later to a higher level like the Gustard A26.......or. Having said that, I have not personally heard the PRO so take...

Now that the D400 Pro has joined the party. I am very curious to hear if anyone has direct knowledge of comparing the pro, versus the EX, versus the ES. I’m thinking/guessing the Pro will be closer to the EX and above the similar priced ES ?

AFtesht: These are just guesses and needs verifying but D400EX: Mentions triple chip design, has (2) AK4499EX DAC chips, and (1) AK4191 DAC chip, CK-03 clock. <6W of power of power consumption. Perhaps uses (1) AK4499 chip for each channel. D400 Pro: Has dual chips and CK-03 clock, looks like...

Joesph, To help narrow down things and possibilities, can you please try doing the same thing but using a coax digital cable from Red into the Holo DAC instead of USB and see if that helps or do you get same symptoms?

Someone please correct me if I'm wrong but I believe I read somewhere that the Red CM4 has 2GB of ram.

Just a following up/add on brantome's answer and Yes, he's correct. But you also need to be careful of the quality of the cable and cleanliness of the cable and ports being plugged into. High res music files are very sensitive to this, many have complained of pops and crackles sounds when trying...

I have the Rose 150B and have tried quite a few other streamers including having had the Aqua LinQ (buggy). Is the 150b pricey? Yes it does appear that way when you don't have one but after you have your hands on one all I can say it's been sheer joy to use and worth it. I have Roon, Qobuz and a...

I totally concur and having Wiim Pro being Roon ready is a huge plus for existing Roon users, including myself. It's add's more potential & legitimacy to the Wiim, just wished Roon was more economical but this has nothing to do with Wiim, as they easily offer one the best deals in hi-rez streaming.

Sadly, there is a good point to this. How many Wiim’s can you buy per year for the cost of using Roon annually with a Wiim? I already have Roon and already bigger existing streamer system so it makes more sense but not so much if your only budgeted for a Wiim.

Marcus, May I ask, since you're getting the streamer from Magna, why didn't you choose one of there own? the Mano ULTRA Music Streamer for around the same price or less; they also have the new mkIII with a LPS for a little bit more, seems like a very nice piece for the price especially when...
