New turntable SRA questions


Hello I am very new to vinyl. I bought a Technics SL-D2 that was in good shape but the mat was hard and oily. I bought a Hudson HI-FI rubber mat to replace it. At the time, I didn't know about VTA/SRA. I measured the old mat at 4.2mm and the new one at 2.6mm. This TT does not have a VTA adjustment. Will that difference damage my records or will it just sound worse? Or is it ok? My records still sound great and everything looks OK to my eye. Any advice would be greatly appreciated. 

 

My TT setup: Technics SL-D2 with Audio-Technica VM95e headshell and cartridge.

Just place a "thick" LP under the new mat (really thick would be around 2mm/really thin would be around 1mm) and see if it sounds better after readjusting the VTF.

The VTA of the stylus comes first, IMO.

I've owned many, many, many decks with SME arms, without the arm being totally parallel to the disc/platter, and they all sounded super once I dialed in the VTA.

I assume that "parallel" may be a bigger factor on some arms, but I have not experienced such with my older (various) SME's.

rwkn22:

SME is a manufacturer/brand.

My various models have/had adjustable tonearm height (seems yours does not), but they (my older models) are tedious to adjust.

I'm picky, but also practical (meaning old and lame), thus using a shim mat for thinner LP's works for me.

The thinner LP's sound brighter (lighter in the LF's) if I do not use the shim mat to raise them.

You may experience the same (fuller sound) by trying a shim mat (an LP under the current thinner mat in your case - as it's an easy zero cost experiment).

The Grado cartridges I use are more sensitive to VTA VS the old Sure V15III cartridges I used to use.

Anyway, if it sounds good it is good.

1.5-2 mm makes a big difference in SQ with my current deck/cartridge (same with the past ones).

As adjusting the arm height on my current SME 3009 non-improved is a PITA I set it up for average thickness LP's and I use a lifter/under mat for thinner LP's (the thinner one's are generally "import" LP's from Europe issued in the 70's/early 80's).

I'm currently using the first version of the Grado Gold Prestige (previously used the Silver version).

All styli have been OEM.
