How to proceed?

@decooney

Thanks, Duane. Yes -- I realize the only way I’ll know is to try it myself. To be honest, at this point, I’m feeling a bit overwhelmed by suggestions... hard to know what to try first.

I’m not after uber-detail. I bought the Hegel primarily for its bass grip and then discovered it significantly (in tandem with Jay’s) upped my systems resolution. At first, it seemed a revelation but over time, it’s become fatiguing. Familiar story, I know. My point is that I would gladly trade some resolution for musicality.

@stuartk do you have anyone locally who’s running either a Pass Labs or a Luxman integrated? May be you can bring that over and try it?

I still think the cable swap will tame that sibilance but ultimately it will either have to be the amp or the dac or both. 

@audphile1

Ironically, I live in the town where Pass was located for many years yet  know no one who has a Pass integrated. ;o)

I’d much rather replace the dac than the amp. My inclination is to sell the Aqua, try a Border Patrol and as you’ve suggested, try other cables.

You never did answer the question on cost for a new DAC (or I missed it). I have found Denafrips DACs (specifically the Pontus II, Terminator II, and Terminator Plus), to be extremely musical and almost tube like; yet perfectly detailed. Denafrips DACs are also a perfect pairing with the Jay's transports, connect directly with a high quality I2S (HDMI) cable....and the I2S pin outs match.

They unfortunately do not have a demo policy. There is a used Terminator Plus 12th for $4,800 at US Audio Mart....with free shipping. That is a steal that I'd buy for myself if I had the funds ready.

@stuartk hit me with the few tracks where you hear this sibilance. If available on qobuz and tidal, I’ll check what they sound like here. Can do it tomorrow I’ll be foggy today with the New Year celebration LOL
