In my case I have a wife and three kids, but don't have a dedicated music room. I sold off my valve amp and gave my speakers away a few years ago and lived with iPhone and AirPods - yeah, they sound crap (Pro's not sooo bad), but recently pulled-out the Mini-Matric DAC I was using with my hifi, installed Audirvana (tousling from MacBook Pro) and plugged in my HD600's (which were being used on the electric piano up to that point), bought new ear pads, head-band and foam pads for the HD's to refurbish them.
But then, of course, when you jump back to something more revealing and precise, then you start listening to the equipment rather than the music and I felt that this combination was sounding rather harsh and really tiring. Even worse, because of the open nature of the HD's, I had to turn them up so loud to drown-out the noise from the family that it was becoming unpleasant.
So I first started looking for a new DAC. Initially I was thinking of a valve-headphone amp with integrated DAC, the Quad PA-One+ was on my list and the Woo Audio WA7, but getting hold of these in Belgium, certainly during C19 lockdown seems impossible. I stumbled across the TA-ZH1E, which looked interesting and tried to buy one cheap from Amazon, but it turned out to be a scam (I realised early enough). During the course of searching for reviews, I somehow stumbled across the NW-WM1Z and loved that it was so stupidly expensive, and gold, plus seems to have a analogue/value sound to it that I like. Under normal circumstances I'd never drop that kind of money on a "walkman", but I've done rather well on the stock-markets these last few months. I first ordered the WM1A as I found it for a good price on Amazon NL.
By pure luck I searched other EU Amazon stores and found the WM1Z for €2000 from Spain - even less for me as I'm VAT registered. Seemed to me that I would no longer have to mess about with streaming and my MacBook, but I could also use it away from the family, in the bedroom, so would solve the HD600 open-back issue. But then one thing lead to another and I ended up ordering the 1ZR's too, on the basis that I could listen anywhere due to closed-back. And then I though "screw-it" and ordered the TA_ZH1E too. The 1ZR's were relatively cheap from Amazon UK at £1350, the ZA from Amazon FR €1450.
The NW-WM1Z arrives va UPS tomorrow - the rest is supposed to be end of next week... Can't find the IEM-1ZR's for the moment, stocks are low everywhere due to C19, but I'm not ruling-out getting those at some point. If the TA- doesn't add anything I'll return it - that's why I like Amazon for these things.
So sorry for the long post, but you have the full story now. Will be interesting to see how the 1Z sounds with my HD600's, if it can drive them, they're 300ohms, I think, so need some juice...
