New Leckerton UHA-6S MKII Portable Headphone Amplifier Announced (Update User Impressions Added... - Page 105

Hi chaps, with respect to the amp-side only, has anyone managed to do any comparisons of the UHA-6 MkII with the Apex Glacier, JDS Labs C5, and/or Vorzuge AmpDuo?

Cheers in advance.

According to some reviewer(ID remember who), UHA has better mids while Apex has better bass. Treble wise, Apex is sweeter and UHA is more accurate.

The real beauty of the UHA-6S is when you channel your music through either its optical or coaxial ports. The USB implementation is not as good. The one thing I wished it had was a line out.

thats why people go with DF or DacPort LX , optocal consume a lot of power, way way more than the USB.

So, instead they have two devices that they have to keep charging separately? Who are these people?

I think they are choosing other DACs because they like them better or don't have a player with an optical/coaxial output.

The other category of ppl are those who want to connect to the iPhone (where the CCK doesn't work). So the CypherLabs Algorhythm Solo, VentureCraft DD, or Fostex HP-P1 (who don't like their amp portion) as their iDevice DACs.

If you're swapping, look for either OPA627AP or OPA627BP.

And definitely be careful of fake OPA627's on eBay. It's best to purchase from an authorized distributor. Try looking at Digikey or Arrow.

I would be careful of those. The places Bill-P mentioned are reputable, as is Mouser. Make sure it's an authorized distributor.

No need to solder. The DIP-8 will plug right in. SOIC-8 needs the adapter. Wherever you buy from, just make sure it's the "DIP-8" configuration.
