  4. GIESELER Groß DAC Review

    Thanks Snoopy - spot on! Working on the web site right now so expect to see an updated site very soon.

    RE - next person to try the demo unit. Tony currently has it (Box Hill) so when he is finished who (Davin, Michael & Russell) would like to pick it up next? Once you decide I will email you Tony’s contact info.

    Hi guys, none of my DAC’s support DSD via S/PDIF. I’m not certain but I don’t think many DAC’s do. However DSD should be fine via USB from the Squeezebox. The Amanero USB board is currently flashed with the default firmware which gives Linux & Windows based server support. For users with Linux based servers I would normally flash the Amanero with the Linux specific firmware which gives better performance on Linux servers & DSD 512. Maxium output of the DAC is 2v rms so with some low sensitivity power amps you may struggle a bit with low level material. As Snoopy correctly pointed out the distortion actually drops a bit at the higher output levels so it is fine to be runing at say 100 - max output.
  7. Hi Peter unfortunately I did all the work in one go so it’s hard to say how much difference just the new clock made. I did have stock CD 42 which I compared it too & you could easily pick the modified one as sounding better. Probably four or five years ago now so hard hard to remember all the details.
  8. SOLD: EOI: Gieseler dual-output Linear PSU - 9V x2

    Hi John, just helping out with the technical info on this dual PSU. OK - both outputs can have their voltages set to: 7.5v 9v 12v this is easy to do by removing the lid & simply moving a PCB jumper which has the voltages clearly marked. Current available is 1.5A per output. There are also jumper setting for 5v & 15v for both outputs but with some specific conditions required. 5v - the internal regulators would be dropping a lot voltage for this output so I would only recommend this for low current use - say .5A or less. 15v - the PSU will output 15v with the current 12v supplied transformer but only at low current say .75A or less. However I can supply a 16v transformer which would then allow higher currents at 15v Cost $45 to $75 depending on the current required. Linear PSU's with series regulators are always a bit of a juggling act in terms of input output voltage ratio otherwise you get too much heat. There are two DC leads with this supply. One using a 5.5mm dia barrel with a 2.1mm centre pin - this suits most units in the voltage range up to 9v eg microrndu, USB regen ect.(red trace lead) One using a 5.5mm barrel with a 2.5mm centre pin - this normally suits higher voltages units (12v or 15V) eg Auralic Aries ect (white trace) Note you need to check with the manufacturer on the DC plug size as these vary with no set rules. Well guys hope this info helps.
  9. OK this was a fair while ago but I’m fairly certain this is the mods/upgrades that were done. Main digital & analogue PSU sections. Replacement of the bridge rectifier diodes with low switching noise Schottky types. All filter capacitors replaced with Panasonic FC’s & values increased. Main clock The simple crystal setup was replaced with a Vlabs low jitter clock module running from a new seperate PSU At the same time I usually did a basic mechanical service - clean lasted & lube meck.

    Hi Mike, yes I will add you to the list & check for your email in the morning.

    Spot on Bill!
  13. GIESELER Groß DAC official release

    Hi Lloyd, yes the the web site does need a serious update to reflect all the current products. It is very slack of me that this has not happened yet. We are in the process of changing hosts so once that happens we will do a brand new website which will be fully up to date with all the current products. Hopefully within a month.

    Great! I will flash the Amanero with the default firmware that way you’ll be able to play native DSD 512 From JRIVER no problem at all

    Thanks for that - so is JRIVER runing on a PC based server or Linux unit?
