Doug, very resourceful actions on your part. All I can say is that if you like it in that setting, you are in for one hell of a nice surprise when it gets put in your new rig.
You will definitely not even believe what that 901 will do when it is on the appropriate arm and table. You probably heard about 30% of what that cartridge is truly capable of. The Teres 265 and Silver/with HiFi mod will give you pretty close to as much as you can get from it.
I predict that you will be stunned beyond belief, and will be posting incomprehensible ravings on this page when it happens. And I am not exaggerating about that. The difference between what you played last night, and what you are about to assemble is a huge, night-and-day kind of difference. You didn't even have the cartridge impedance loaded right, had insufficient gain, and a turntable/arm combo that is not even in the same universe with the Teres/OL/HiFi combo. You are going to go stark, raving mad in a few days, so we will be patient with your babblings of ecstacy. I would love to see the look on your face on that first night that you fire this rig up.
Word of warning! READ THE INSTRUCTIONS!
You have to assemble the platter into the bearing properly before you play. This requires the oil to be put very carefully into the bottom of the bearing, without getting any on the side walls of the bearing. Use a large eyedropper that is made for giving infants medicine, that is graduated in milliliters on the eyedropper body.They have them for a buck at the drug stores. The Teres bearing needs 5ml of oil from the bottle supplied. Now when you put that platter/spindle into the bearing, it is going to take 12 hours for it to settle into position. YOU MUST NOT SPIN THE PLATTER OR TRY TO PLAY THE TURNTABLE BEFORE THE PLATTER SETTLES COMPLETELY. Let it settle into the bearing on its own overnight or about 12 hours, until the platter is about 1/4" above the plinth. DO NOT TRY TO RUSH THIS PROCEDURE. Once the bearing has fully settled and you can not push down the platter at all, and it doesn't feel spongy, and it is about 1/4" above the plinth, then you can play. No matter how anxious you are to hear the table, you must follow these directions, and I don't mean maybe. Do the platter seating procedure last, after you already have the plinth placed on whatever stand it will be on, and leveled. Trying to move a Teres around after the oil is in and the platter is on, will result in spilled oil, I guarantee it. I know you will want to play the table right away, but forget about it. You have to wait until it is ready. Put the plinth where it will be and level it,put the thrust pad in - teflon side up, put the 5ml of oil in with the medicine dropper, and put the spindle(with ball bearing inserted)/platter assembly on, and wait until it is ready. Then play, probably the next day. 8 or 9 hours ain't gonna get it. It takes at least the full 12 hours to get fully seated. It has very tight clearances, and you will damage it if you don't follow these rules.
You made a good choice by getting the Silver Mk1 arm. The Mark 2 has a very stunted set of weights on it.
