I really like the Cayin HA-6A. It is an incredibly high-quality and beautiful thing. It gives different sound characters by changing the lamps and switches on the front panel. It is the best on the market.
The HA-6A is leaps and bounds better than my previous headphone amp. I'm still in the burn-in phase but so far, this amp is very resolving, very detailed and imaging is great.
Instrument separation is also great. It's very easy to distinguish each instrument and there is no blurring/merging of sound coming from each instrument in the output and the timbre, for each instrument, is very accurate. One thing to note at this stage is soundstage depth could use improvement but with headphones that can be very difficult to attain.
It's a tube rolling paradise and difficult, at this point (still in burn-in), but I can't wait for time in each to day to go through my library to listen to how much better this amp is compared to my previous, only a several hundred dollar, tube hybrid amp.
The team at Bloom were a joy to work with and answered every question I had regarding this amp.
Thanks, again, Bloom Audio for all of your assistance in helping me decide which amp best fits my tastes and budget. Well done and I look forward to working with you again!
