Advice/Warnings for a newbie


Hi

I've had way too much free time and gone down a few rabbit holes purchasing some older gear, some of which I've got a little experience with and some none... but was curious, because I am not the best technically, if any of the more seasoned audiophiles might have any advice regarding my chain. I'm replacing my 30w Pioneer receiver with separates (put all my specs in the below list) – I got the preamp as a family hand-me-down and I've just bought the monoblocks (having service done now) so I've not heard it all together yet. The player and speakers I've been using forever. But will I OK in terms of matching impedances, gain, etc? Oh, and I'm installing a dedicated line for the monoblocks and was looking at a Niagara 1200 as power conditioner for the rest.... any tips greatly appreciated!

At the risk of being "neurotic and gullible"  ;-), the gear you mentioned would certainly benefit with upgraded power cords. I do, however suggest that you get everything setup, working and some time listening to the system before you change anything. Get a feel for the system sound, then if you want, experiment with power cords, interconnects and speaker cable. Actually, I have found that power cords make very good changes to the sound of the overall system. IMO, Pangea and Signal cables are not good choices as they have produced a dull or muffled effect on the gear I have tried them with. There are many choices out there and one does not have to spend a fortune to get good results. Kimber, Zu and VH Audio have good value/performance offerings.
roberjerman cannot hear these differences, so he makes claims, these differences do no exist. They do exist, just listen for yourself, and with the system you put together, it will not be hard to hear. 
Thank you all, very much appreciated.

Should have mentioned cartridge is next on my list to move up with, had actually been looking at Hana as well, thank you for the recommendation. I had been reluctant to jump from MM to MC just yet, (I did buy that phonostage in particular for its gain versatility) but was going to edge up toward the top of Nagaoka MP500 line (which does drop voltage from 4.5mv to 3mv and extends high frequency response from 20k to 25k). Thankfully being a lifelong DJ I have a second identical player at my disposal so I plan to have a vinyl buddy over and shoot out some carts A/B. I don’t want to overstep my player with a cart.

I didn’t mention ICs or power cords yet, just because wanted to see if anyone saw any red flags elsewhere like the 100w class A with that 90db speaker efficiency (that’s middle of the road in terms of efficiency, right?).

IC’s - I tried not to break the bank while finding my footing in that world. I had to get some Fischer > XLR ICs made (was repeatedly advised Cello String were not worth my time, and I don’t want to mod the Cello for XLR outputs in case it doesn’t stay in my chain, rather keep it original) so I have Steve Huang at AudioSensibility make those using his Statement SE cables. He also made Phonostage > Preamp ICs with the same. Was planning on sticking with him for power cords for the turntable power and Preamp (need both regardless) but for the Alephs I read from Nelson Pass that they don’t need anything fancy:

“The power draw of this system is constant regardless of the music playing through the amplifier. As such, it does not depend on a high quality AC outlet or special power cords, since the dynamic performance does not create a variation in AC line draw. If the AC line is running low, the output stage will bias to a higher current level by way of compensation.”

Of course it’s a 30 year old amp, but I figured as long as I get them onto their own dedicated circuit and off the default circuit that shares with my fridge and stove (can actually hear disruptions in the sound when the stove ignites) then that’s at least a start.

Speaker cables, I’m currently using Kimber (gift from a friend when I got the speakers).

As for the Niagara, after lurking on these forums for a while now, I expected these reactions. Was also looking at the Shunyata Hydras, but again, not a priority.
hook the system up first as-is and take some serious time to listen and enjoy.  Then start listening for anything you feel may be missing or off, if that exist at all.  I don't think it will be much.

Then, and only then, start playing around with the tweak/upgrade path if you feel it's necessary. 

Don't upgrade/tweak willie-nillie.  If, after some time and experience, you feel you aren't quite "there" yet, then start with the tweaks/upgrades.

Very nice system.

enjoy
