Should I consider the newer Audio Research pre & power amps, when I play records not CD's


I worked in and owned upper end audio stores back in the 1970's. (McIntosh B&O Magnepan, etc) I have been pretty much out of audio for the past 30 years. In my old age, I want to play the records I have saved (many MFSL & Japanese virgin vinyl) I kept my B&O linear 4002 W/mmc20CL cart. and it still works and I have newer B&W 804 speakers. I am going to get a new table of better quality. I have always wanted an Audio Research tube amp and Preamp. I am considering the LS 26 or LS17SE Preamp and older D90/115 or newer VS 115 or the Ref 75SE. I am in my 60's and my hearing is not as good as it was, plus I am lost with all the digital technology. (just started using a smart phone) I just wanted to get opinions spending $4000 on older ARC or bite the bullet and spend in the $7000 up. Is it worth spending the money for the new equipment when I am only playing records.

I have found that over the years system synergy has a huge impact on your sound.  Make sure to take a holistic approach to your system, not just a "that's the best component". Unfortunately, only by a lot of work can you start to dial-in the synergy unless you copy completely a system that you have heard and liked.  I have had approximately 20 preamps (both tube and SS including an ARC SP-6b and an SP-10) and 30 amps (both Tube and SS including two D-115 mkii's and a VT200).  I listen to vinyl almost exclusively. I LOVE the flexibility of tube gear.  To warm, roll-in a brighter tube, to bright, get a warmer one).  Since you are focusing on vinyl, I would seriously consider the classic tube phono amps of the 80's. ARC SP-10 and SP-11 mentioned earlier as well as any CAT or Counterpoint. The phono stages were awesome and most can be had fairly inexpensively- by far the best price/performance. In my current set-up, I am taking the phono stage of a CAT out through the tape outputs to the line stage of a Doge 8.  Simply magnificent, much better than the CAT or Doge alone and better than the recent gear I have heard (although most listening sessions also introduce other variables (components) that I don't have a gauge on, so hard to make an educated assessment.  Also critically important are the tube choices for each- 60's Amperex 6922's for the phono input and 60's GE 12AT7's for the line stage.  But the bottom is, after a LOT of searching I am now happy with my system.   I have been focused on tube amplification for the last couple of decades and until recently my favorite has been my ARC D-115 with winged C power and the same 60's 6922 Amperex's. But I have now moved to a low power SET tube amp driving my M/T 8ohm loads and an ARC SS 100.2 driving the 4 ohm bass enclosure. Cost on all this was pretty reasonable (as if any of this is reasonable) of about $4k for used CAT and new Doge preamps with NOS tubes and $4k for the new SET and used SS amps.  Whatever you choose, enjoy the music.
one thing I forgot to mention regarding phono stages (and system synergy) is that almost all of the preamps I have heard require either an external or have an internal SUT to get the most out of a low output moving coil cartridge.  So, (in my biased listening preferences opinion) if you are going to get a cartridge that has an output < or = .5mv you are going to need an internal or external SUT.  The newer CAT's have them built in, not sure about the newer ARC's, but none of the 80's preamps have them.  The phono sections of all those will work, but for me they are too noisy and lack the preferred weight.  I currently use an EAR MC-4 with a Benz or accuphase LOMC (which I now prefer) or a koetsu SUT with a rosewood signature if I am listening mainly to vocals.
"only playing records" !!! Sumbuddy git a rope!

I owned the SP8 and 10 - loved them both, with Atma-Sphere tube amps and Bryston SS. Then the DIY bug bit, and I found myself too old to roll tubes.

If you must have tubes, consider Atma-Sphere. Their amps have no output transformers, so sound extraordinarily clean.

And since you are "only playing records" (gasp!), you must (repeat must) get something to clean them. Otherwise you will (1) wear away your stylus prematurely, costing serious money in your league and (2) never hear your records to anything near their potential. I use ultrasound - and it is not over the top for anyone with a $10,000 analogue front end.

Good luck!

You might look up various amps and gear on stereophile.com.  I've found their reviews to be really good.  They usually include some serious testing reports as well.  I always thought ARC was great gear, but I went for McIntosh instead.  For a digital music server, I recently bought a Bluesound Vault II.  It will digest your CDs into its hard drive and you can control it via an app on your tablet or smartphone.  It connects to your stereo amp, or preamp, over RCA, or digital coax, or fiber optic.  I have mine connected to my McIntosh C47 preamp via digital coax.  Amp is MC402 hooked to Wilson Sophias.  It's a great setup.
I am trying to get rid of, at least part of the rope. When I started my quest to play records again, I was not aware of the advances that had been made in digital music. I can remember the first time I compared a CD (2 by oversampling) to a record, it was like listening to AM radio. My experience now is only with an ipad using Bluetooth thru the system in my shop. I did dive into learning more about digital music and with the help of Lostbears started to understand the ins and outs of playing digital music. A streamer is on the have to have list, after reading everything regarding them. I still very much want to play records and well aware of keeping them in good condition. I have over 500 LP's and all are in rice paper sleeves, cleaned before and after use, and I take the static out before and after. Compared to Digital it is a pain. That being said, It is going to hard to beat listening to Pink Floyd, Dark Side, on MFSL UHQR, a glass of wine or Grand Mariner, except I have to get up and turn it over. Then after it is played, clean it and put it away and get out the album I want to hear next. I can see how it would be easy to get spoiled sitting in your listening chair with an Ipad to select what you want to hear. Not to mention a favorites list.

I try to take the time to research each of the systems you'll have, mainly to educate myself. With most of the new stuff (mainly Digital) I have much to learn. 

Thank you for all the options. Any experience with Aurendar or Lumin streamers?
