ESS is coming out with a new chip that will integrate MQA fairly soon. I am hanging on to my current chip to see how the new ESS chip is received.

BGA (Ball Grid Array) are usally soldered to the motherboard.

I was thinking a passive stand alone radiator. http://www.frozencpu.com/products/21234/ex-wat-269/Aquacomputer_Airplex_GIGANT_1680_External_Radiator_-_Copper_Fins_33302.html?tl=g30c95s667#blank You would just have a pump running.

I have only listened to Zappa' CD's some remastered and some digitally recorded vinyl. Does the high res sound a lot better?

Seems DPLL bandwith is is the is the only thing in the firmware that would change the sound. What is DPLL bandwidth? Why would going from default to the lowest setting makes a big difference in sound?

You could check out Frozen CPU. Liquid cooling is pretty effective and quite.

What about a Lithium iron phosphate battery (Life Battery). Wouldn't that be cleaner than the alkaline? Was thinking about adding one to digital side of a DAC.

I am using this configuration to setup the chip: bin/bash -e dac_upd() { V=`i2cget -y 1 0x48 "$1"` V=$(( (V & ~$2) | $3 )) i2cset -y 1 0x48 "$1" "$V" } ### input remapping #dac_upd 14 0xf0 0xf0 # enable dac_upd 14 0xf0 0x00 # disable (default) ### jitter reduction dac_upd 10 4 0 # bypass and stop #dac_upd 10 4 4 # enable (default) ### SPDIF autodetect dac_upd 17 8 0 # disable #dac_upd 17 8 8 # enable (default) ### use best DPLL dac_upd 25 2 0 # disable #dac_upd 25 2 2 # enable (default) ### DPLL bandwidth #dac_upd 11 0x1c 0x00 # no dac_upd 11 0x1c 0x04 # lowest (default) #dac_upd 11 0x1c 0x08 # low #dac_upd 11 0x1c 0x0c # med-low #dac_upd 11 0x1c 0x10 # medium #dac_upd 11 0x1c 0x14 # med-high #dac_upd 11 0x1c 0x18 # high #dac_upd 11 0x1c 0x1c # highest ### Quantizer and Differential mode #dac_upd 15 0xff 0x00; dac_upd 14 0x8 0x8 # (8ch) 6-bit true (default) #dac_upd 15 0xff 0x55; dac_upd 14 0x8 0x0 # (8ch) 7-bit pseudo #dac_upd 15 0xff 0x55; dac_upd 14 0x8 0x8 # (4ch) 7-bit true #dac_upd 15 0xff 0xaa; dac_upd 14 0x8 0x0 # (4ch) 8-bit pseudo dac_upd 15 0xff 0xaa; dac_upd 14 0x8 0x8 # (2ch) 8-bit true #dac_upd 15 0xff 0xff; dac_upd 14 0x8 0x0 # (2ch) 9-bit pseudo ### IIR bandwidth #dac_upd 14 0x6 0x0 # PCM normal #dac_upd 14 0x6 0x2 # DSD 50k (default) #dac_upd 14 0x6 0x4 # DSD 60k #dac_upd 14 0x6 0x6 # DSD 70k I don't understand most of it, but it makes a huge difference for me. Would it run on a 9028 or is that a different beast.

Would upgrading from a 9018 to 9028 make a big difference in sq? The Dac is a Twisted Pear Buffalo SE. I already have the Mercury analog section installed. Cost would be about $365 as I need 1 regulator plus the board. The 9038 is also an option, but with its higher voltage, I would have to replace regulators and change the resistors on the line stage. Thanks.

If you want to spend a few bucks Phoenix Contact make a good USB cable. It's about $70 on Digikey. I believe it is USB on Firewire. I wouldn't goof around around with expensive USB cable unless they have a complete Data Sheet of their specs. Otherwise who knows what your are buying.

I think it's up to the individual to make decision on cables. A good quality cable should last a life time, unless you have a Great Dan pup. Sent from my SAMSUNG-SM-G935A using Computer Audiophile mobile app

Way off on 35k they are 500k. Interesting about the noise on a non balanced line. I have a Dahlquest LP1 crossover would that work plugged into just a DAC? It actually has volume for each channel too. Sent from my SAMSUNG-SM-G935A using Computer Audiophile mobile app

M-Audio also makes some nice PC speakers. Sent from my SAMSUNG-SM-G935A using Computer Audiophile mobile app
