It’s a fair and valid question. What I like about what Mitch does is that he listens to his reference tracks and albums for at least a week before taking multiple measurements with his system. Some of the tracks and albums he uses are those where he was the recording engineer, the man at the...

Danny at Raal-Requisite said he will do this once the first batch of customer orders has been satisfied.

Very happy with my Utopia 2022/SP3000 partnership. When I add the PA10 it also works well with the ZMF Caldera. If I didn’t already have the Utopia I would also look at the AA Composer and the Erzetich Charybdis, both of which are available to audition at my reasonably local dealer.

Since the SR-1a was first released at the end of 2018 there have been a number of people who have discussed the ribbon drivers in comparison to the main Stax protagonists. Most recently @simorag has shared comments about Immanis and the Warwick Aperio. The comments are there if you’re prepared...

I think if you can imagine a cross between the SR-1b and the 1266TC with 8 ribbon drivers per side in an octagonal configuration, all individually motorised for millimetre perfect angling and distancing, you might have an idea of what it could be like. Add to that a DSP-based App, fully Roon...

I’m not home for the next few weeks so unfortunately cannot look into this further. But I will say, one sight of the word “Harmon” and I’m gone…..I mean I turn into an angry very green individual and want to smash anything and everything associated with that word. I hate it. I appreciate the...

It’s not about volume, it’s about over-driving the original signal so that it distorts. This might be preferred by owners of Gibson Les Pauls and Marshall stacks, but digital signal clipping is horrible and must be avoided. If you boost some frequencies by EQ’ing them it is wise to compensate...

If that’s how you feel right now awaiting Santa Alex’s delivery what are you going to be like in a couple of years (?) when Alex announces the Raal 1995 version of the SR-1a/b? This is not necessarily a factual comment, merely an echo of what we talked about when we met at World of Headphones in...

I think you’ll find those who lay their money down without a demo will mostly be those who already own and enjoy at least one of the previous Raal-Requisite phones. If that’s the case I say in no way should your expectations be curbed. Immanis and Magna take what’s good and very good about the...

Go and have a read and decide for yourself. I know nothing about AutoEQ and what it can do. What I do know is that Mitch uses his experience as a studio engineer and not just technical solutions. His convolution filters are the equivalent of more than 30K parametric sliders when applied to a 48K...

No, the filters can only be stored in Windows or MacOS, and are then made available to the various playback systems that can use these environments. Roon can use these filters simply by ‘pointing’ to where they’re stored. The filters can also be used if I use my SP3000 DAP as a Roon Endpoint...

Have a look at accuratesound.ca Mitch is a former studio engineer who has developed digital solutions for room correction and headphones. Convolution filters are sophisticated EQ solutions that Mitch has developed for individual headphones as a consequence of extended listening and technical...

Tunes, if you can afford to do so I recommend you hold onto the HSA-1b until you have a chance to hear it with Immanis. I had a borrowed Envy at home and had a chance to demo the Immanis for a few days. I personally think Immanis sounds better with the Envy but I also cannot listen to my SR-1a...

Ah yes, I remember now that you got yours ‘at a favourable price’ from Thanatos. Will you and Mr T be getting together at some point to compare the older Mrs Walnut (my name for the Envy I borrowed from Thomas) with the ‘new and improved’ Mrs Walnut AE? That would indeed be an interesting little...
