    Gotten Sick Of Choosing Between Home Theatre and 2 Channel Tube Sound

    This is probably audiophile sacrilege but... I've taken my C2300 and MC-275 Mk VI out of my system leaving me with the following setup: Phono system (where I do most of my listening): MT-5 (with MT-10 cartridge installed) -->MP-1100 Vacuum Tube Phono Preamp--> MX-121-> bridged MC-7106->XLS-340...

    Question On MC-275 Mk VI 12AX7A Tube Swapping V3 & V5

    Hi... I fired up my MX-275 Mk VI last night and unfortunately noticed that the left channel was dead (actually, playing extremely low). Suspecting tubes, I started to swap the various 12AT7's and 12AX7's. I found that when I swapped the 12AX7A's in V3 (marked on the chassis as being for the...

    Sticky Remote Problem Fixed In Replacement Remotes From McIntosh

    My MVP-891's remote was starting to get gooey and sticky, so I called McIntosh to buy a replacement. The Parts department representative told me that they have replaced the old MVP-891's remote (a remote in the HR070 family -- used on most McIntosh devices from the 2000's and had the...

    MR88 Users (and others who have Sirius/XM Radios -- XM Is Free Till Memorial Day

    MR-88 users. If you hookup your XM receiver unit and antenna to your MR-88 and go into Setup (press the Mono button for a few seconds) and enable XM, you can listen for free till Memorial Day. This applies to all Sirius-XM radios.... I think that XM sounds much better on my MR88 than it...

    MR-88 Firmware: Current Version Is v1.11

    McIntosh now has a later release of the MR-88 Firmware that fixes a software bug that I was having with "ghosts" of the tuning indicator being left on the screen as I turned the tuning dial. I was previously using v1.10 which was necessary for XM reception. v1.11 seems to now be common with...

    Shipping McIntosh For Service -- Do You Insure The Shipment?

    I have to send my MR-88 tuner to Audio Classics for some service. I have the original McIntosh packaging for the tuner. I am probably going to ship it UPS Ground. For those of you who have done this before, would you insure the package for the full replacement value (which I believe is...

    MR-88 Problem -- Anyone Else Have Problems With The Bar Tuning Indicator?

    I have a 6 year old MR-88 that just started an irritating yet non-fatal symptom. I was wondering if anyone has experienced this issue. I have had the MR-88 apart and have unplugged and re-plugged all of the various connectors etc on all of the boards as well as doing a "reset" by pressing the...

    Just Bought A Used C2300 -- A Couple of Questions???

    Hi, I just bought a used C2300 for $3500 (I took everybody's advice here and chose the C2300 over the C2200). It'll be arriving on Tuesday.... I'm going to be using it to replace the 2 font channels on my MX-121 Home Theater Controller for my MVP-891 BluRay player, MLD-7020 LaserDisc...

    Opinions On the C2200 -- Does It Have a "Vacuum Tube" Sound?

    There's a C2200 up for auction on E-Bay. I was thinking about replacing the front two channels of my MX-121 so that I'd have an "all tube" path from my phono (MT-5 with MT-10 cartridge feeding a vacuum tube McIntosh MP-1100 phono preamp) to my MC-275 (in stereo mode) amp. Forgive me for not...

    MVP-891 -- My YouTube No Longer Works -- Does Yours?

    Can someone with an MVP-891 try out YouTube and see if they can connect to it? My MVP-891 YouTube never gets past the "connecting" screen.

    Running XLS-340 Speakers With Two Different Amps -- Will It Help Me?

    I am running my McIntosh XLS-340 front speakers from my beloved MC-275 Mark VI amp. I have an extra MC-7100 stereo transistorized amp lying unused in my closet. The XLS-340 speakers have two sets of connectors on each speaker, one for the lows and one for the highs (I guess this is called...

    MC-275 Mark VI Bias Adjustment

    As you may have read in another thread on the board, I had some problems with two blown 220 ohm wire-wound plate resistors. You can read all about it on that thread. On this thread, I wanted to talk about the KT88 tube bias adjustment. The MC-275 Mark VI does not make this a "user-friendly"...

    MC-275 Mark VI Service Manual...

    Due to my problem with the wire-wound 220 ohm plate resistors on my MC-275 Mark VI amp, I obtained a service manual for this model. Most of the ones circulating on the Internet are for the Mark IV. Unfortunately, it's too big to upload to AudioKarma.... If you want a copy, please PM me.

    MC-275 Mark VI -- Left Channel Distorting

    This morning, I noticed that my 1.5 year old MC-275 VI (with all stock tubes) had horrible distortion (mostly in the treble) on the left channel. After doing the normal diagnosis procedures (switch the right & left speakers, switch the right & left inputs from the preamp, switch the right &...

    As a result of my own bad experience with my old MX-119, I want to caution you all about preventing static electricity damage to your treasured systems during low-humidity winters.... Here's what I've done and the caution that I take before touching my equipment... 1) Put in a whole house...

    Just Bought A McIntosh MP-1100 (Phono Stage) To Replace My MP-100

    It'll arrive tomorrow. I'm trading in the MP-100 to Audio Classics (great people to do business with BTW). The MP-100 was a fine phono stage and sounded great, but I have a huge collection of early '50's LP's and old '78's and the MP-100 just wasn't flexible enough to handle non-RIAA...

    How Does McIntosh Put the Little Green Light "Tube Ready" Indicators On the MC-275 Mk VI?

    McIntosh, on their MC-275 Mark VI tube amp, puts little indicators that seem to come from inside the 12AT7 and 12AX7 tubes. The indicators start out with a dark orange color when the amp is first turned on and then they progress to a gold color and finally, when the amp is ready to play, the...

    Damn You MC-275 Mk VI -- Why Do You Entice Me Back To Tubes????

    I just replaced the front two channels of my all-McIntosh surround system with a new MC-275 Mk VI (my system consisted of the MX-121, MR-88, MT-5, MP-100 Phono Preamp, and MVP-891, bridged MC-7106 for the front three channels -- the MC-7106 now handles the center and two back channels). The...

    Has Anyone Seen Or Heard the New McIntosh Tube Phono Preamp???

    I believe the model number is MP-1100. It's supposed to be the end-all of phono preamps with the ability to properly equalize early 45's/LP's that weren't recorded with the RIAA Equalization curve and 78's as well. I believe that it's priced at $8000. I bought the model that they introduced...

    The Power Amplifiers MC-7100 and MC-7106

    I decided to bridge channels on my MC-7106 amplifier resulting in 3 mono channels of 200 watts apiece which I'm using for my Front-Left, Front-Right, and Front-Center channels (I mostly listen to 2 channel stuff anyway). I was thinking of buying another amplifier, the two-channel MC-7100 to...

    Bridging McIntosh 7106 6 Channel Amp -- Can I Combine The Back Channels?

    I have a McIntosh MX-121 feeding a McIntosh MC-7106 6 channel amp and five loudspeakers (no subwoofer). The vast majority of my listening is stereo CD's and stereo LP's. I only occasionally play surround sound movies. I do not have, nor do I want a subwoofer (I am very sensitive to bass and...

    The New MP-100 And Dealer Availability...

    I didn't know this, but there seems to be a "class" of McIntosh dealers that are allowed to sell McIntosh models such as the new phono preamp MP-100 new and with warranty via mail-order. I was unaware of this and was under the impression that McIntosh forced a customer to buy from his local...

    http://www.mcintoshlabs.com/us/Products/pages/ProductDetails.aspx?CatId=phonopreamplifiers&ProductId=MP100 This product seems like a dream device for people who have a turntable. The ability to switch to mono and the variable "loading" for MM and MC cartridges are really exciting. I can't...

    What Is the Cartridge On the McIntosh MT-10 Turntable?

    I know it's a ClearAudio made cartridge, but I'm curious if it was designed and manufactured specifically for the MT-10, or whether it can be purchased separately. Thanks for any info that you might be able to provide...
