    The Darlington Labs thread (New 2024 models!)

    Note that when shipped, the unit is set to Mode=MM, and with MM gain at +40dB. This means that the extra +26dB (which is the stock "as shipped" setting for the LOMC internal step-up -- there are two separate gain blocks) is not in circuit. The manual contains wording for each combination of...

    Equipment Recommendations - The Home For New System and Upgrade Advice

    We've made remarkable progress while remaining within the 5 inch chassis and in the MP-7 model and pricepoint. We continue to evaluate the next step up in our line in this regard. Balanced output option is being explored for an MP-7 variant and potentially dual-mono regulation.

    MoFi UltraDeck / StudioDeck Owners and those interested

    We've been asked this very question regarding the new breed of cartridges available in a 1.0mV LOMC and 4.0mV HOMC flavor from Hana and from Grado and others. 1.0mV is rather hot for an LOMC and so our SU-7 has a +12dB mode especially suited for this. In any case, if a qualified individual or...

    Amp cuts out using headphones

    The Pyle PP-999 is notably better than your 555, in that it has a flatter frequency response. When we say we've evaluated our competitors "fully", that includes a 200x price range, and it includes **3** Pyle units, the PP-444, PP-555, and PP-999. A **regulated** 24VDC power supply may help on...

    Grado Cartridges and Stylus - Questions and Advice.

    We have a partial solution to the VAT question. Per a buyer request, we can detach the front panel and ship the unit as an "incomplete/parts unit", declaring only the cost of raw components, because in this case, as is, it would not be a retail-saleable item. No duplicate invoice will be...

    Darlington Labs MM-6 USA Tour

    Probably not soon. We have an SU-7 coming out, and maybe we could think about that. If you have an existing Low-Output Moving Coil cartridge, it can be used "together with" your own existing preamp, putting that existing preamp in a "MM" mode (lower gain). Basically it functions as an active...

    Thank you. We are particularly interested to hear user reports of cartridges where they are offered in a 4mV high output version and a 1mV low output version, otherwise being as similar as possible - Grado and Hana as examples. Sales stats from dealers would be interesting too. There are...

    May we ask what is piquing your interest at a level above the $800 Musical Fidelity MX-VYNL that appears to be your current preamp? To our knowledge, the MP-8 would be unique in the marketplace in being a unit targeting higher-output cartridges out of the box, thus allowing a user the chance to...

    Darlington Labs MM-6 USA Tour

    At the present time we're not scheduling an MP-7 tour. We sent a demo to Anthony because he had extensive experience with a number of other competitive preamps in his system, and compared the MM-6 to these. He expressed interest in hearing the MP-7 in this same system and comparing it based on...

    We are planning on sending you that demo unit around mid-January. Sales picked up and we did some work on the upcoming matching SU-7. More production capacity is now online.

    EE Master's or even PhD programs probably aren't suited to turning out the next John Curl. Analog isn't taught in depth. Decades of practical and iterative research and a sensitive ear are important. We hope that the Chinese-clones-on-eBay-board manufacturers consider it witchcraft, however.

    Darlington Labs MM-6 USA Tour

    We would be happy to send you a demo MP-7 for your comparison, since you took the time to put together such a nice comparative review and have had extensive comparisons previously, if you're willing to report on the results to the forum. We can add the optional switchable "gain up" modification...

    Now, what is the receiver brand and model in the back of the beginning of that ad?

    For models with the Mono switch, the GND post is normally on the right hand side near the AC power connector (viewed from the back). This is due to space constraints. Normal models have the GND post on the left-hand side near the input jacks. On a special-order basis, we could built a unit...

    Understood. And, it could end up being that for some reason, IF you need to use the A/D->DSP->D/A room processing etc, and therefore HAVE to digitize your phono inputs, that the more limited built-in phono preamp is better because it is rolling off details or because they "voiced" it to work...

    Do you have another system available, maybe even a friend's system, whereby you can take your TT and cartridge, then A/B using your Marantz receiver purely as a Phono preamp, meaning just take its "Tape Output", and then the MM-6 Line Out, and compare those two.

    You might also consider the effect of "listening fatigue" on the A/B. Meaning, we find that you can run our units much "hotter" than the typical built-in-IC-phono preamp found in these receivers. So, consider matching volume by "how high you can listen before you wince". This is probably more...
