Super Best Audio Friends

Had this in the house roughly for ten days. Shortly speaking, the amp was surprisingly good to me.

• I argue an ultimate headphone amp should drive and sound like ECP DSHA-3F. Proximity to that specific product is largely the way how I rate headamps.
• I've consistently shown my dispreference toward opamp-based headamps. Also strongly believe that excellently measuring amps are all shit. None of Heresy, Atom, 888/789 worked for me, although heresy was noticeably better than the rest.
• As of early July in 2020, Jotunheim seems regarded as a flavor of two or more years ago. I am a member of the minority group who still likes Jot over similar alternatives such as 789. Amps listed in the second bullet point were worse than Jot in one or multiple criteria. At least for the headphones I enjoy.

I'm a bit late on this one since the Ara seemed to steal the thunder from the 2020 update to the Andromeda. Physically the dimensions are unchanged, so those with fitment issues with the nozzles being too shallow with the OG Andromeda won't find this any better. The only change that I've noticed from the OG is bore opening is a grill instead of three holes.



I will keep the subjective impressions short. While the OG Andromeda (without much tweaking and from a near zero ohm source) has a slight V-shape, the Andromeda 2020 is a dark sounding IEM. Actually quite a bit darker than the measurements below would indicate. The highs up top do sound a bit more refined, but I am not sure if this is via the tweaks since the OG Andromeda (applied to Solaris), or a function of the FR differences (more lows and less highs).

I ordered my own unit a few days ago and it should be here by the end of the week. I will post more detailed impressions but I was curious if anyone else has heard this amp.

I've been asked this a few times now so I figured I would share with how I constructed my balanced to single-ended converter using line input transformers. The sonic reasons for doing so are to provide an alternative sound for DACs which have a balanced (XLR) output where you have an amplifier or preamp that only takes unbalanced or single-ended (SE) inputs (RCA). Some DACs such as the Schiit Modius have a balanced output which is a different circuit from the SE outputs, so this method provides another option. I will not guarantee that using the converter will sound better, only possibly different. For example, if it sounds better, then all the power to you. In some instances, such as with pro audio gear DACs, we will have no choice because pro gear usually does not come with SE outputs.

The iFi Phono3 is absolutely insane. I don't even know where to start or how to explain, so I figured I will make this another one of those stream of consciousness reviews with measurements along they way. Like other iFi products, the Phono3 offers a ton of user adjust-ability, except in this case I feel it's warranted. To borrow a phrase from someone I had just spoken to regarding the Phono3, the Phono3 is geared for the tweaker or perfectionist!



I'll start first with how it sounds and keep it short and sweet. The first thing I noticed about the Phono3 is how clear and free of veil it sounded compared to practically all other phonostage unless they were super high-end or special custom jobs designed for a specific use case. iFi says the Phono3 is direct coupled design, and it certainly sounds like it. Most phono stages will have several caps in the signal path, even disregarding the caps...

I'm about to go full Al Gore on you guys because this is a discussion topic i have wanted to flesh out here for a while now
if you love music, and i mean really love it, not just as background noise - why are you still bothering with D/S converters? I feel as though there has been an increase in discussions and interest regarding D/S DACs on this forum in the past two years. I attribute this mainly to two things:

1) PRO AUDIO MEMES FOTM (AKA 50 SHADES OF GREY)
2) ASR

my perspective after 4 years
your perspective

I know all of this has been hashed out to some extent one way or another before, but i feel like an honest and stark refresher is in order. i know there are several community members who had similar experiences to me, and i would like to ask anyone who messed around with D/S converters in the past and settled on R2R as the righteous path to share their experience.

SO, YOU HEARD VINYL IS AWESOME AND SOUNDS AS GOOD OR EVEN BETTER THAN THE BEST DIGITAL?
These latest discussions are why I am super hesitant about getting folks into TTs. It's going down the rabbit hole that either leads to wonderful or severely messed-up results. It's Lucy in Sky with Diamonds and Are You Experienced. You have absolutely no idea what kind of trip it's going to be.

Figured it might be time to post about what I've been doing with the TH900. I've tried about a million things with these, and the pictures I'm going to post are pretty much the best I could get them before I decided to use wood glue to permanently screw the cups in place. Not because they're perfect, but because I had already crossed the line into insanity and needed to preserve my own mental health. The tuning I arrived at was as close to perfect as I could get for my tastes and given these headphone's strengths. No, they'll never have the imaging of some open headphones, and they'll never be dead flat. But for tactility and slam with a fun tuning that still reveals mixing choices and recording differences with ease, I haven't found better. Lets just say this is the headphone that is making my 3 pairs of HE6 sit and collect dust.

I couldn't find any dedicated thread for this amp, so I thought I would share my thoughts on this pretty sweet amp! TLDR: I think this is a great all rounder solid state amp that is "reasonably-priced" and can provide an alternative flavor if you find the Black Widow too warm and lush sounding. For me, this is the perfect place holder amp while I patiently wait for Starlett to arrive on my doorstep.

First off, this is one of the few solid state amps out there that synergizes well with HD800. no joke, even the stock HD800 was sort of listenable which really surprised me. What was even more surprising for me was that it wasn't a warmpoo amp trying to mask all the flaws of HD800, rather play to its strengths without messing up the FR too much.

The way I am going to approach the UltraLite mk4 is from a headphile and working-from-home perspective. The Ultralite is a computer interface with multiple inputs, multiple outputs, internal routing, mixer, DA/AD, and more. It's a viable alternative to the RME ADI-2 Pro (remember when it was FOTM). I only wished that someone had brought this piece of gear forth as a much less expensive alternative with a different sound. @Psalmanazar has mentioned this, but the RME's FOTM had already passed by the time he did.



The quick takeaway is that the Motu Ultralite mk4 is the bees-knees best-thing-since-sliced-bread at an affordable price point of $700. It does everything we can possibly imagine and more. It serves as an excellent DAC for the price point.

Notable highlights:

• Employs es9016s 8 channel DAC
• Excellent performance, especially considering price and size
• Dynamic Range > 130 dB This surprised me as Motu specifies 120 dB
• Gain Linearity tight to -110 dBFS then less than ± 1 dB to -130 dBFS
• Channel Crosstalk is exceptionally low with separation > 145 dB Bal and > 128 SE
• Possibly highest performance / price ratio pro audio interface existing at the time of this post
• Has earned duty in my pro audio setup replacing RME Fireface UC for most lab and studio functions

OK. F me. Seriously F me. I didn't mind the Velvet Sound that much when the AKM Velvet Sound DACs came out. Heck it was mostly cheap DACs, so who cared. The immediately noticed benefits of greater resolution and more expansive soundstage seemed to outweigh the disadvantages. However @Psalmanazar pointed the Velvet Sound stuff out early on; and over time, I actually grew to dislike the AKM Velvet Sound.

I didn't think this possible, but from the Modius' balanced outs, this Velvet Sound stuff is no longer. Or at least none of the disadvantages of the Velvet Sound (murky lows, recessed mids, soft attacks, raised last octave) but with all its advantages (resolution and expansive soundstage). Holy cow, this actually sounds like the older Modi 2 or other AKM4399, 4495 based DACs with the crisp attacks, evident mids, more palatable highs, bass textures, punchy bass even! After what seems like years, it's so nice hearing the E and A notes on a guitar not sound as they've been processed through a blender.
