I wonder if anyone has the option that the type of music one listens to affects one's preference for type of amplification? Personally I don't find the latest generation of class D amps sound clinical or sterile. However my listening tends strongly to the Classical genre that might demand a...

True, I dare say. I bought a Purifi 1ET400A-based stereo amp from the bargain assembler, VTV Audio. I bought it with Hypex' Evaluation I/O buffers. At higher volumes the treble sounded unbearably shrill and unnatural. I quickly replaced them with VTV's own buffers (designed by Sparkos) with...

I listen with my ears. However I find a very high correlation between the sound I like, (detailed, transparent and with deep, articulate bass), and ultra-low distortion components. In terms of amplification you can get these qualities in a US$2000 amplifier that will drive virtually any...

Technology advances, surface-mount components, and robotic assembly have made high-quality drastically cheaper nowadays. Purifi and Hypex have proven that astronomical price isn't what delivers better results. In fact super-clean ultra-low distortion amplification has essentially become a...

Is anyone really questioning a person's right to listen to any amp technology they enjoy? I think not. I do appreciated our OP linking us to Ralph Karsten's comments. Ralph made highly regarded tube equipment for years and still does. Ralph's reputation and achievements make his opinions...

I'll confess I didn't have the patience to struggle through REW to derive a FIR filter. Fortunately I got wind of Gsonic which is extremely easy to use and does a great job, (at least it did for me). A couple of Gsonic references ... ASR Gsonic thread

I believe there are increasing numbers of DACs and streamers that incorporated FIR convolution filter files, though most can't create the file. You can use a computer NOT connected to any of these device to create the FIR file, then transfer it to the DAC/streamers via a USB stick. The same is...

Again, in my personal experience this seems to be case. Although results may vary slightly amongst those who create & apply FIR filters, most will benefit significantly. In my case the cost of making this very large improvement was zero given I already had a calibrated microphone that cost <$200.

AH!! Thanks. I hadn't notice that. A key insight is that the usual objectivists considers standard measurements "settled science" and definitive of everything we need to know. Risbos objects to that. It's amusing to see him say that the 'Objectivist Tribe' consider pretty much everything...

I don't think there is a whole lot mystical about it. Q: What is a good recording in terms of sound quality? A: It is a recording that consistently sounds good to me regardless of the equipment on which it is played. Q: What equipment reproduces a good recording closest to the inherent...

I have no experience with very high-end components such as the Von Gaylord UniPre so I'm unqualified to comment on the improvement such a component might make. The sound I hope to achieve is the raw, unmodified sound of the recording itself. The first & fundamental problem is that some (many)...

Sonic penalty? Well a sonic difference to be sure. I love my Sonic Frontiers Line 1 and will swap it back into my setup from time to time. The Line 1 produces a slightly warmer, smoother sound than ultra-low distortion components but with the loss of some detail and, maybe, a very small...

In my case ran my power amp from the Eversolo dispensing with a preamp. However I wanted to continue to run Foobar2000 on my Win computer because I like Foobar's browse to access my NAS-based music library. I wanted to use USB to send Foobar output from computer to the Eversolo. USB to...
