Via the T+A Dac200, an ideal partner for upsampled DSD, PGGB DSD512 offers significant improvements over the PCM version based on early listening. There's lots of options (different upsampling "types") but based on 1 step upsampling red book to DSD512, this is pretty special.

I dragged myself back from the precipice of 64bit/32fs too. Life's too short even with a fast computer to process and a 20tb hard drive.

I'm not sure if you've tried selecting no processing in HQP and playing the PGGB files directly (HQP is very good just as a player for these upsampled files as it's gapless playback is excellent). Sounds superb, but I also like the Closed-Form filters. Also - especially is you're using DSD, but...

I only have experience with Rephase (free to download as part of Room EQ Wizard). I don't have time to prep a full tutorial, but basically there are multiple tabs. In one of which you can create an frequency eq curve to suit your requirements. There is a separate tab which shows how the...

Your experience aligns very well with my own. My own EQ curve (fabricated over many iterations in Rephase, which allows correction of phase also) is very similar to yours, but with a little extra weight in the low end because I don't use passive baffle step correction (I don't like the result of...

Ribbons being such low impedance require lots of current, very little voltage. As I recall JotR can deliver 13 amps (at low voltage). OTL tube amps tend to be quite high resistance, so are current-limited, swinging higher voltages to deliver what power they can muster. Transformers are a great...

JRiver, as I recall, allows VSTs to be loaded - a convolver VST could then run the filter.

Except of course they do:beerchug:. PGGB has exactly that functionality, I do exactly that. It's not a perfect paradigm, especially for those who use multiple headphones and systems (files prepped for an SR1A with a decent bass lift won't play nice with already bassy headphones or speakers), but...

Hi - I was wondering how you find the bass of the SR1a with the Envy? My hankering after a nice tube amp is strong but I haven't yet had a chance to listen to the Envy and I don't want to go out of my way to audition something with a flabby bottom. I know the Kallyste Amethyste offers a taught...

I am intrigued by the two new Raal offerings and I hope they meet the very high expectations Alex has set, but as RLawry nicely said above, one of the big appeals, driven by the format of the SR1a, is the presentation that comes from the lack of a cup. There are some excellent cupped headphones...

I have to say I tend to keep the wings close to my ears, not touching but not spread out. I don't notice much difference in soundstage but the extra weight in the bass tends to suit my preference.

I've been using a combined PGGB/HQPlayer approach for a long while. I use PGGB to upsample everything to 705/768ks at 64bit (maintains the best accuracy and minimises noise shaping). HQPlayer then converts to DSD using Poly-sinc-Gauss-xl and a 7EC modulator variant. Volume control is disabled...

I believe the Jot R has no output transformer. It is possible to make an output circuit that will handle the current required to handle the impedance, but it's not common.

I saw a comment from the Solaja owner saying he was ceasing VM1a production to focus on new projects (that 300b amp Aleks mentioned recently in this thread). OTOH, Headphone Auditions in Amsterdam, NL told me earlier this week that VM's are available on a 45 day leadtime. I am still debating...

WHat's the lifespan of VM1-a tubes? Anyone have any firm data?
