    What a nice unit. Have always been a fan of NAD, ever since having discovered the gear often used in studio and in radio stations for monitoring the transmitter. Love the external heat sink, the display and the no-nonsense design. I also spy a Picquic screw driver. Love those things! I have a couple here at the house and a couple at work.

    geeze, hate to jump into that same old controversy - - just can't resist - - CD vs Vinyl - - on reference quality playback gear, one can expect near equal "sonic" results, yep, there's differences alright, but it's closer than most listeners and even some audiophile types are aware of - most, if not all listeners and engineering types that want to argue that point simply don't have daily access to true reference playback equipment - - the problem for vinyl, beside the investment in cost in order to equal whatever level of digital playback a person is using, is what everyone already knows, it's a delicate medium, stupidly delicate compared to CD's - hell, even the same "pressing" run can produce varying sonic qualities. Personally, I really like both digital and vinyl playback, wouldn't want to give up either and yes, I have RIDICULOUS money invested in vinyl playback vs my digital gear so I wouldn't argue that digital easily wins in the cost category, no contest at all. WAY more bang for whatever the given buck. Given all that, the primary key to good or great vinyl sound is the quality of that "delicate" record itself.

    @@skip1835 I have bought vinyl LPs and 45s for years, and there is an audible difference in the audiophile pressing, and the normal LP. Play both on the same Hi-iFi system the first time each, (i record them immediately) and the difference in dynamic range is obvious, (for young enough ears). The audiophile has quieter quiet parts and more distinct "louder" passages. Could I confirm that they were better than CDs, no because CDs were not around when my ears could perhaps have discerned the difference. But I suspect yes, the audiophile vinyl LP would sound nicer, clearer and better than a "normal" CD. (not sure if they issued audiophile CDs, as they were already supposed to be the "ultimate" in sound. I do know my cassettes recorded from those LPs still sound mighty fine to these older ears.

    anyone have experience or knowledge about how to fix a NAD 7125 which losses its station presets? When power is turned off, and then turned back on all the station presets are lost. Assuming this is something to do with the non-volatile memory either being bad, or perhaps a capacitor that needs replacement. However I can't figure out where to look, etc. Thanks in advance!

    If memory serves correct those ones have a super capacitor it's generally located on the board somewhere I don't remember exactly because they're all different but it's a really large value. Typically 1 farrad at 5 volts or less. I have done one if you look you will find a video search my channel for super cap replacement because I did one I forget what model it was but they typically have a super capacitor either that or lithium battery. Here is the link to the bad 7155 I did the supercap on. kzread.info/dash/bejne/pKN61stsddK4mKw.html

    The records in my collection are in pretty close to MINT condition. The ones I use out in the shop for testing are records that would never be played on my Technics SLM1 or Thorens TD165. Records I still have from when I was a kid are pretty beat up. My old Beatle records have seen better days, because I got most of them when I was 5 years old and had one of those sebreeze flip down record players with the BSR changer and tone arm that weighed 15 grams. When I started buying my own records as a teen, those ones are like new. The ones I use out in the work shop on turntables of unknown quality are all old ones that I was given from the TV station I worked at for a few years when they cleaned house and tossed their old production music records.Most have 2 or 3 records stuck into one sleeve because that is how they were treated in the production truck. I have only shown a couple of my records. One was the comparison video where I compared a Mobile Fedility to a commercial pressing. My records are in mint condition because I never play them. Any of them. They sit in a cabinet. The last time I played them was when I digitized all of them.

    BS. Every play a vinyl wears slightly. Nothing can prevent that. The tip of the stylus is heated to several hundred degrees just from the friction of being dragged through the groove. The changes are very slight between each play but they do wear. CD doesn't wear, and a good CD player, with a properly mastered digital copy will run circles around any vinyl. Unfortunately many have been hood wined into believing that vinyl sounds better, and spend thousands trying to achieve that perfect sound that they will never get.

    You really don't understand how any of this works. With the newest stuff, NAD is using Hypex output stages with hybrid filtering. Both in measurements and in listening, they have proven to be great, natural sounding amps. Yes old NAD stuff is excellent. Great sound and I love the simple no-nonsense design. This is why you'd often see a NAD receiver at radio stations, being used to monitor the transmitter. I myself have an NAD C368 integrated amp, which uses the Hypex output stage. Sounds incredible, and I have picky ears. As things progress, never just label things bad because of whatever technology is used.
