The price is markup expensive exterior design and the very small series and they dont get obselete, if more people wanted this stuff it could be built in china for a fraction of the price, but i bought it anyway after much hesitation :) The HD621 is not the main processor it is a hdmi switch and signal converter to MHR so that my old G68J processor that does not have hdmi can use the signals . And yes both my processors have some sort of jitter attenuation the hdmi processor the most as many hdmi sources have *really* large amounts of jitter I would not call the humax dtv box i have high end . But that is the whole point , all digital *sources* are the same to me . The processor is still not obselete due to the add on HD621 for hdmi , you also get that for the money digital stuff that does not get obsolete for decades . Meridian processors are not unique in their capacity to suppress jitter everything has it nowadays I bougth the processor and DVDA player in 2004 it migth have been rarer and costlier back then . But it is bit apples and oranges , the complete meridian system works like this the DAC's are in the speakers so the processor does room acoustics processing and subwoofer xover and surround sound fields and tone controls and source selection the processor in turn have special digital outputs for meridian speakers and a control bus for volume etc so the cross overs in the speakers are digital with all kids of corrections and eq for the drivers there is one DAC per register in each speaker and one amp per element in the speakers . I have no clue to exactly what dac's they are . But it seems to work as far as i can tell . So processor actually buffers 100's of milliseconds of data and there are some latency in the speakers too and of-course MHR and speakerlink how does that work ? the specs are not open . So there is much more to a Meridian system than "jitter" the whole architecture is correct , I've yet to find another system that is thats Meridian strength it is a complete system . What do I mean by that, theoretically a DVDA disc has 144dB s/n quickly turning it over to analog directly in the player is just silly and not how you should do it ,kiss >40dB sn goodbye . In my case the SQ loss happens first in the speakers when the DAC for each element kicks in there are practically no loss in sound quality in the chain before that . that was unique in 2000 when Meridian had this (well they had it for CD resolution in the 90's ). Nowadays with the latest HDMI variants many of todays HT recievers have this you player can send CD/DVDA/SACD/Bluray in all kinds of resolution directly to the receiver . this was not very common back when DVDA/SACD was released a decade ago . Now Meridian still have an unique selling point in their digital speakers that takes this further . So yes the mass-market homet heater stuff are gaining ground , the high end are still stuck in there tube an cable fetish ? BTW Meridian operates mostly in 24/88.2 or 24/96 the speakers are limited to that, and the G68J and HD621 down converts if needed ( they can receive such signals ). Why is that ? Meridian has the opinion that higher resolution does not gain you anything at all it would only make the equipment cost more as it should do all this DSP with 2*memory and CPU and not sound any better . Whats missing IMO is an open digital speaker protocoll . at least active analougue speakers are becoming more common for home environment so in a couple of decades more a home theater/hifi may actually have a decent basic architecture . The passive speaker paradigm was obsolete in the 70's so who are ludites in this realm :) and not wanting the best technology for the jobb . Imho the conservatism in the audiophile circles have at least kept back the development 40 years if not more . Ok cables the MHR link requires rj45 conectors and have the same impedance as ethernet so you use normal cat5e cables and yes I dont use brand name ethernet cables here , i use patch cables I found on the supermarket . ------------------------------------------------------------------------ Mnyb's Profile: http://forums.slimdevices.com/member.php?userid=4143 View this thread: http://forums.slimdevices.com/showthread.php?t=96407
